This system has been proven in our record setting race cars to be the strongest Subaru head gasket system ever produced. To achieve these results, our engineers separated the combustion chamber sealing from the fluid sealing aspects of the head gaskets. Our machinists carefully machine a lip at the top of each cylinder to accept the \"Fire-Lock\" ring. With the ring locked in place, it stands firmly above the deck, providing a superior seal. The separate gasket bodies take care of sealing oil and coolant passages, while keeping them out of the combustion chamber. 14mm Head studs hold the assembly together.

In an effort to continue offering an extremely popular and proven product to the Subaru community, IAG approached LIC in early 2020 with the intention of expanding their offerings to IAG’s growing network of retail and wholesale clients. Once terms were agreed upon, some very minor design tweaks and adjustments were made to the product.\u003c\/p\u003e\n\u003cp\u003eThe timing idlers were developed and extensively tested and proven in the LIC Time-Attack program. Over the past decade the eccentric idlers have become the installer’s standard in both street and motorsports applications, playing a helpful role in bringing cams back into proper alignment with heads or blocks that have been resurfaced or feature thicker head gaskets.\u003c\/p\u003e\n\u003cp\u003eThe IAG Performance Adjustable Timing Idler kit is specifically intended to properly align the camshafts on Subaru EJ20\/EJ25 cylinder heads and\/or blocks that were resurfaced (“Reducing” long block length), or utilize thicker head gaskets (“Increasing” long block length). The ability to adjust and properly align the cams is recommended for any performance built Subaru.\u003c\/p\u003e\n\u003cp\u003eThe product is precision CNC machined and hand assembled in-house.

When that process is done it effectively retards the timing, because the belt has not changed length and something needs to make up that difference in the slack (the tensioner can only do so much).

IAG has developed a process to greatly improve the strength of the OEM Subaru FA20 Case Halves to combat the effects of high cylinder pressures brought on by increased power and boost. Our proprietary \"Closed Deck\" System works by supporting the top of the cylinder in the weakest areas and prevents movement and expansion which can lead to cracks and failures. Despite the additional material supporting the cylinder walls, there is no concerns with overheating or coolant flow because the area around the middle of the cylinder still maintains the same coolant area. The custom IAG closed deck inserts are machined with holes for oil and coolant to pass through the same as stock. Each IAG 800 FA20 BRZ\/FRS\/GT86 Case includes machining for 1\/2\" head studs and a cylinder gasket \"o-ring\" groove to aid in head gasket sealing. If you're one of those people who prefer to do your own builds we now offer our legendary closed deck case halves for purchase separately. Simply install your crank, rods, and pistons to your own specifications and be confident that the case halves will take the power and prevent common cylinder wall failures.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"IAG 800 FA20 Closed Deck Case Machining\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/Unknown-870.jpg\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eTHE IAG CLOSED DECK PROCESS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eThe IAG Closed Deck conversion is performed 100% in-house by our engineers and experts using state-of-the-art equipment. The IAG Closed Deck starts with a new OEM FA20 bare case. The case is loaded and fixtured to a 4th axis rotary indexer in our Haas VF4-SS CNC Vertical Machining Center. It is supported by the main journals using a precision ground 2-inch bar and tailstock which ensures the datum is the main journals. This method gives us a true reference point to perform all machining operations. A Rennishaw probe is utilized to check that the case is fixtured true, and once confirmed the machining process begins. \u003cbr\u003e\u003cbr\u003eOnce the case is fixtured, the first step is to mill out pockets for CNC inserts. Rather than attempting to install inserts into an inconsistent cast case, the pockets are milled out to exact dimensions creating a consistent area that accepts our precision inserts. Once the pockets are machined, the case is removed from the mill and placed into a block oven at a low temperature. Our pre-machined closed-deck inserts are simultaneously chilled using dry ice. When the case and inserts have reached our desired temperature, they are moved into our install station, which holds the block and lightly presses the inserts into position on one side of the deck surface. This process is repeated on the other side and then the partially completed case is moved to a cooling rack. In the next step of our process, the case is loaded and fixtured back into the VF-4SS after reaching room temperature. During this stage, the flanges left from machining the inserts are milled close to the case deck surface. Features such as coolant passages and case bolt access positions are machined. Finally, each deck surface is machined true and flat using a Poly Crystal Diamond insert.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"IAG 800 FA20 Closed Deck Case CNC Inserts\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/Unknown-873.jpg\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eSPECIALLY DESIGNED INSERTS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eOur machining process converts the FA20's open deck to a complete closed deck and features the use of cast insert material that closely matches the metallurgy of the aluminum case material in a factory Subaru FA engine block.

START HERE\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eIt's no secret that the OEM Subaru case halves, or \"block,\" aren't exactly the strongest. IAG has developed a process to greatly improve the strength of the OEM Subaru FA20 Case Halves to combat the effects of high cylinder pressures brought on by increased power and boost. Our proprietary \"Closed Deck\" System works by supporting the top of the cylinder in the weakest areas and prevents movement and expansion which can lead to cracks and failures. Despite the additional material supporting the cylinder walls, there is no concerns with overheating or coolant flow because the area around the middle of the cylinder still maintains the same coolant area. The custom IAG closed deck inserts are machined with holes for oil and coolant to pass through the same as stock. Each IAG 800 FA20 DIT WRX Case includes machining for 1\/2\" head studs and a cylinder gasket \"o-ring\" groove to aid in head gasket sealing. If you're one of those people who prefer to do your own builds we now offer our legendary closed deck case halves for purchase separately. Simply install your crank, rods, and pistons to your own specifications and be confident that the case halves will take the power and prevent common cylinder wall failures.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/Unknown-877.jpg\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eTHE IAG CLOSED DECK PROCESS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eThe IAG Closed Deck conversion is performed 100% in-house by our engineers and experts using state-of-the-art equipment. The IAG Closed Deck starts with a new OEM FA20 bare case. The case is loaded and fixtured to a 4th axis rotary indexer in our Haas VF4-SS CNC Vertical Machining Center. It is supported by the main journals using a precision ground 2-inch bar and tailstock which ensures the datum is the main journals. This method gives us a true reference point to perform all machining operations. A Rennishaw probe is utilized to check that the case is fixtured true, and once confirmed the machining process begins. \u003cbr\u003e\u003cbr\u003eOnce the case is fixtured, the first step is to mill out pockets for CNC inserts. Rather than attempting to install inserts into an inconsistent cast case, the pockets are milled out to exact dimensions creating a consistent area that accepts our precision inserts. Once the pockets are machined, the case is removed from the mill and placed into a block oven at a low temperature. Our pre-machined closed-deck inserts are simultaneously chilled using dry ice. When the case and inserts have reached our desired temperature, they are moved into our install station, which holds the block and lightly presses the inserts into position on one side of the deck surface. This process is repeated on the other side and then the partially completed case is moved to a cooling rack. In the next step of our process, the case is loaded and fixtured back into the VF-4SS after reaching room temperature. During this stage, the flanges left from machining the inserts are milled close to the case deck surface. Features such as coolant passages and case bolt access positions are machined. Finally, each deck surface is machined true and flat using a Poly Crystal Diamond insert.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"AG 800 FA20DIT Closed Deck Case Inserts\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/Unknown-880.jpg\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eSPECIALLY DESIGNED INSERTS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eOur machining process converts the FA20's open deck to a complete closed deck and features the use of cast insert material that closely matches the metallurgy of the aluminum case material in a factory Subaru FA engine block. By using a similar cast material (rather than billet), we ensure that during expansion and contraction the materials grow and shrink at similar rates, which is vital for maintaining roundness within the top of the bore. The inserts are machined from ¾\" cast material.

The assembled case halves are machined in our Haas VF-4SS CNC mill to accept IAG Closed Deck inserts, then the block is heated while the inserts are cryogenically cooled so they can be pressed into place for a secure mechanical fit. Once installed, the deck surface is machined to a smooth, mirror finish. Each insert is designed with built-in coolant passages so proper flow to the deck surface is maintained, meaning you get the added strength of a closed deck without sacrificing cooling performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cimg alt=\"IAG FA20F 1000 Series Closed Deck Short Block Parts\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/42ea0511-7a81-4121-a254-55d7e27c68a3\/-\/format\/auto\/-\/quality\/best\/\" style=\"display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003eBUILT WITH 100% NEW COMPONENTS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eThe IAG 1000 FA20 DIT Subaru Closed Deck Short Block for the 2015–2021 WRX begins with brand-new Subaru FA20F engine case halves that are precision-machined in our Haas VF-4SS CNC mill to accept IAG Closed Deck inserts, converting the factory open deck into a much stronger closed deck foundation built to handle serious cylinder pressure. Once the inserts are installed, deck plates are bolted on, and the block is bored and honed to 86.25mm using our Sunnen cylinder hone, allowing us to dial in exact piston-to-wall clearances for proper ring seal, quiet operation, and reduced oil consumption. While it’s on the mill, we machine a groove at the top of each cylinder for the Fire-Lock head gasket system and drill the head bolt holes to accept 14mm head studs. From there, the case halves are assembled with a brand-new Subaru FA20 DIT crankshaft, IAG-Spec H-Beam forged connecting rods with ARP 625+ rod bolts, and ACL or King Race rod and main bearings.

To achieve these results, our engineers separated combustion sealing from the oil and coolant sealing functions of a traditional head gasket. Each cylinder is precision-machined with a counterbore step at the top to accept the Fire-Lock ring that mechanically locks into place and creates an extremely secure combustion seal. The independent gasket bodies handle sealing the oil and coolant passages, keeping fluids out of the combustion chamber where they don’t belong.

This solution is loosely derived from diesel technology, where a counterbore step is machined around each cylinder bore, allowing specially sized fire rings to drop into the machined area and head gasket bores. The shims are designed to create a compression seal once the heads are installed and torqued into place. IAG fire rings are manufactured to a very strict tolerance from a proprietary alloy and are then put through a heat treatment process. The gaskets are manufactured from an asbestos-free composite raw material and feature a silicone-based beading applied to critical areas to improve sealing around all water and oil passages. The combination of the alloy compression shims and gaskets assures maximum sealing for a Subaru FA20 turbocharged engine.\u003c\/p\u003e\n\u003cp\u003eThe IAG Fire-Lock gaskets require machine work for installation and are recommended for use with 14mm head stud hardware.\u003c\/p\u003e\n\u003cp\u003eThe gaskets are sold in pairs with four Fire-Lock rings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"text-align: center;\"\u003eOIL PICKUP\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eOil pickups are a critical failure point in the FA20F engines, especially when pushing your Subaru to its limits. The factory pickup can lead to severe engine damage or catastrophic failure due to the screen dislodging under high oil pressure, allowing debris and even fragments of the screen itself to enter the engine. Subaru’s design is also notorious for restricting oil flow, creating the potential for oil starvation. The IAG Performance Oil Pickup for the 2015-2021 FA20F WRX is designed to solve these issues. With an enhanced design that improves oil flow and durability, it offers a dependable solution to the common problems with OEM oil pickups.

IAG-Spec H-Beam rods with ARP2000 rod bolts are utilized, along with King or ACL rod bearings. The case halves are sealed with new OEM case bolts and sealant.

These 2618 T6 Alloy high-strength pistons have been specifically designed to support increased cylinder pressures which come with more boost. FSR forgings reduce mass and wear caused by friction without sacrificing strength. This is accomplished by using an asymmetrical skirt design instead of the traditional full-round skirt, also this reduces weight significantly. Featuring smooth flowing radii on the domes and dishes, the design promotes excellent flame travel. The pistons are secured to the rods with .905 x 2.250\" x .210\" wall carbon steel wrist pins with Tru Arc locks. Note: This block features 12.5:1 Standard Compression pistons which are ideal for lower boost or stock applications.\u003c\/p\u003e\u003c\/div\u003e\n\u003ch2 style=\"text-align:center;\"\u003eNEED HELP CHOOSING A BLOCK?\u003c\/h2\u003e\n\u003cdiv class=\"video-embed\" style=\"position:relative;width:100%;padding-bottom:56.25%;height:0;overflow:hidden;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/AMytJ0EHOZo?start=0\u0026amp;end=0\u0026amp;autoplay=0\u0026amp;loop=0\u0026amp;rel=1\" allowfullscreen loading=\"lazy\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eWe made this video to highlight the differences between each of our short blocks and to help you choose the best one for your performance goals and budget.

Then the heads are fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's standard size 36mm Intake and 32mm Exhaust valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate, which cuts the aluminum to a smooth, even finish.

The Centroid CNC ports the intake and exhaust runners under the valves and blends them to the valve seat. Once the Centroid completes the port process, the heads undergo a cam clearance machining process which removes material from the lifter area where larger lift and duration cam profiles are known to contact the castings. The heads are then fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's standard size valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate, which cuts the aluminum to a smooth, even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process. Finally, the heads are reassembled using IAG Stage 1 Single Valve Springs and Titanium Retainers along with GSC Viton stem seals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cimg alt=\"IAG 750 CNC Pocket Port Cylinder Head\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/c75893c5-fbe3-4fa8-9257-bd624d4640ba\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eWHAT IS A POCKET PORT?\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003ePocket porting is enlarging and blending the area under the valve seat.

The bare castings are visually inspected then fixtured into our in-house Centroid 5-axis CNC Machine. The Centroid CNC ports the intake and hard to reach exhaust \"dog-leg\" port runner. The benefit of CNC porting is not only an efficient way of machining the heads it also offers consistent port results that are hard to achieve by hand. Once the Centroid completes the port process the heads undergo a cam clearance machining process that removes material from the lifter area where large duration cam profiles are known to contact the castings. Shortly after the heads are drilled to fit larger 1\/2\" or 14mm head studs, which are commonly used in high horsepower builds. Next, the OEM guides are pressed out and replaced in favor of GSC Manganese-Bronze valve guides that are shaped to improve airflow. Once all the new intake and exhaust guides are in place they are diamond-honed in our honing station.

FA20 Heads are configured differently from their EJ counterparts. In FA20 heads the casting is split into two parts, the \"lower\" and the \"cam towers.\" As the name suggests, the \"Cam Towers\" hold the camshafts to the cylinder head.

The bare castings are visually inspected then fixtured into our in-house Centroid 5-axis CNC Machine. The Centroid CNC ports the intake and hard to reach exhaust \"dog-leg\" port runner. The benefit of CNC porting is not only an efficient way of machining the heads it also offers consistent port results that are hard to achieve by hand. Once the Centroid completes the port process the heads undergo a cam clearance machining process that removes material from the lifter area where large duration cam profiles are known to contact the castings. Shortly after the heads are drilled to fit larger 1\/2\" or 14mm head studs, which are commonly used in high horsepower builds. Next, the OEM guides are pressed out and replaced in favor of GSC Manganese-Bronze valve guides that are shaped to improve airflow. Once all the new intake and exhaust guides are in place they are diamond-honed in our honing station. The heads are then fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's +1mm valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate which cuts the aluminum to a smooth even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process.

It can be done by hand with a die grinder and some cartridge rolls, and a seasoned professional can likely get a good result that way. Unfortunately, doing porting this way requires a lot of experience and care. One slip of the die grinder can ruin your cylinder head. This is where CNC porting comes in. Using our Centroid 5 axis CNC porting machine we can achieve the same results every time we put a set of heads into the machine.

(Just in case you want to go bigger later.) Then the heads are fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's standard size 36mm Intake and 32mm Exhaust valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate, which cuts the aluminum to a smooth, even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process.

These CNC pocket ported heads provide a significant upgrade in flow over the IAG 600 heads. These heads work great for cars with some race track duty (road, rally, auto-x, drag) and are designed to support up to 800 BHP with supporting mods. These heads include upgraded GSC +1mm Stainless Steel Valves, GSC Viton Valve Stem Seals, Upgraded GSC Valve Guides, Kelford Dual Valve Springs with Titanium Retainers, and OEM Keepers. FA20 Heads are configured differently from their EJ counterparts. In FA20 heads the casting is split into two parts, the \"lower\" and the \"cam towers.\" As the name suggests, the \"Cam Towers\" hold the camshafts to the cylinder head. Kelford \"A\" cams are available with IAG 800 Cylinder Heads. When Kelford cams are chosen we also include new OEM cam towers, rockers, pivots, and valve shim caps.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"Newen Seat and Guide Machine Machining IAG Cylinder Heads\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eBUILT WITH 100% NEW COMPONENTS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eEach IAG 800 FA20 DIT Cylinder Head Set starts with new OEM castings from Subaru of America.

The heads are then fixtured into our in-house Centroid 5-axis CNC Machine, one of the most advanced precision engine machining equipment in the world. The Centroid CNC performs a \"pocket port\" of the area under the valves, enlarging and blending the opening under the valves. The benefit of CNC porting is not only an efficient way of machining the heads it also offers consistent port results that are hard to achieve by hand. Once the Centroid completes the porting process the heads are drilled to fit larger 1\/2\" or 14mm head studs which are commonly used in high horsepower builds. Next, the OEM press-fit freeze plugs are removed, to avoid a common known failure in which they loosen and leak coolant into the engine oil as well as externally. To eliminate this problem each head is tapped and threaded plugs are installed. At this point, GSC Manganese-Bronze valve guides that are shaped to improve airflow are pressed into place then all the new intake and exhaust guides are diamond-honed in our honing station. The heads are then fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's +1mm valves. The heads decks are then resurfaced using our TS-3000 BlockMate that cuts the aluminum to a smooth even finish. To remove debris and oils from the machining process, the heads are ultrasonically cleaned. Finally, the heads are reassembled using Kelford Dual Cylindrical Valve Springs and Retainers along with GSC Viton stem seals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cimg alt=\"IAG 800 CNC Pocket Ported Competition Cylinder Head Package Valve Opening\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/bce7f155-82a7-4072-a6bf-c6782a2bdb05\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eWHAT IS A POCKET PORT?\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003ePocket porting is enlarging and blending the area under the valve seat. This is one of the most critical areas to get right in any porting job. Luckily, our Centroid 5 axis cylinder head porting machine gets it perfect every time. The area about 1\" under the valve is enlarged and blended to ensure a smooth transition and increase power. The rest of the port is left alone because additional volume is not required at these power levels, and can even hurt velocity if there's not enough airflow.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/b449834e-f6f4-469f-b25b-b9d83c2ca221\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eOPTIONAL KELFORD \"A\" CAMSHAFT AND LIFTER PACKAGE\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eIf you're planning for more power you'll want to select these Kelford \"A\" camshafts for your IAG 800 Head Package.

One such measure was the use of pressed in casting or \"freeze\" plugs on the head castings. These plugs are designed to cover the holes left during the casting process and contain the coolant inside the cylinder head. Unfortunately, the pressed in plugs have a tendency to become loose, and if they pop out you'll have oil and coolant mixing inside your timing cover and causing a huge mess and possibly costing you a new engine. We've developed a solution for this problem which involves carefully threading the opening for the casting plugs and installing new, threaded plugs that wont pop out. This is a must when going for higher horsepower in your FA20 equipped WRX. \u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"CEI\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/Unknown-378.png\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eQUALITY GUARANTEED\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eWe stand behind every hand-built engine we produce.
