Trick Flow® GenX® 255 Cylinder Heads for GM LS3
Trick Flow engineers combined the best features of factory GM LS3 and LS7 cylinder heads with Trick Flow’s own unique brand of race-winning engineering and technology to create the ultimate square port LS cylinder head for 4.000" and larger bore engines—the GenX® 255. The heads feature fully CNC Competition Ported runners with a premium high resolution surface finish for maximum airflow and performance potential. The valve angles have been changed from 15° to 12° to increase piston-to-valve clearance and allow the use of larger camshafts. The coolant holes through the head deck were redesigned to work with all LS head gasket and engine block combinations. Stock LS3 ports accommodate LS3-style intake manifolds and LS9/LSA blower assemblies. GenX 255 heads are available with standard and 6-bolt per cylinder mounting patterns. Trick Flow GenX 255 cylinder heads are emissions-legal under CARB E.O. #D-747 for 2007-present GM vehicles with 6.2L engines. They are available fully assembled or as bare castings. Sold individually.

Trick Flow® GenX® 260 Cylinder Heads for GM LS7
GM LS fans, here is a sure-fire formula for making more power: Big bore LS engine + Trick Flow GenX 260 LS7 cylinder heads = huge power in a lightweight package. Trick Flow’s GenX 260 square port aluminum cylinder heads for GM LS7 are designed to meet the needs of enthusiasts using any LS-based engine block with a minimum bore diameter of 4.100". To improve the factory design, Trick Flow added more material to the A356-T61 aluminum castings for increased rigidity and strength. Then Trick Flow improved the valvetrain system by integrating modular one-piece, 2024-T4 billet aluminum rocker arm mounts that are removable for high-end shaft rocker setups. Trick Flow’s high flow, high velocity CNC Competition Ported runners with the premium high resolution surface finish provide all-out air flow and performance throughout the entire powerband. Other major improvements include the available 6-bolt per cylinder clamping for GMPP LSX and other aftermarket blocks, clearance for 3/8" pushrods, through-deck coolant holes to fit all GM LS gasket and block combinations, Trick-Alloy powdered-metal valve guides, solid stem valves, and two Trick Flow by PAC Racing Pacaloy™ valve spring packages. Trick Flow GenX 260 square port cylinder heads for GM LS7 work with all LS7-style intake manifolds. The heads maintain the factory intake and exhaust port locations, valve angles, and valve locations so they work with existing LS7-based pistons. Fully assembled cylinder heads include valve springs, steel or titanium spring retainers, die forged steel valve locks, and valves. They are emissions-legal under CARB E.O. #D-747 for 2006-present GM vehicles with 7.0L engines, and are available fully assembled or as bare castings. Sold individually.

Trick Flow® GenX® 225 Cylinder Heads for GM LS2
These Trick Flow GenX® 225 cathedral port cylinder heads for GM 6.0L LS2 engines are fully CNC-machined to significantly increase the performance of LS2-powered cars and trucks. Trick Flow engineers altered the valve angles from 15° to 13.5° to decrease valve shrouding, increase mid-lift airflow, and improve rocker arm-to-valve cover clearance. Material was added at the rocker arm mounting points to increase high-rpm valvetrain stability. The spark plugs were relocated in the CNC-profiled combustion chambers to enhance mid-lift airflow and increase the rigidity of the casting for extreme horsepower applications. Top-of-the-line CNC Competition Ported runners have a premium high resolution surface finish for maximum flow and performance. Trick Flow GenX 225 cylinder heads are emissions-legal under CARB E.O. #D-747 for 1997-present GM vehicles with 4.8L, 5.3L, 5.7L, and 6.0L engines. They are available fully assembled or as bare castings. Sold individually.

Trick Flow® Twisted Wedge® Track Heat® 185 Cylinder Heads for Ford 4.6L/5.4L 2V
Trick Flow® Twisted Wedge® Track Heat® 185 series cylinder heads are the best aftermarket heads for modular-powered Fords. The secret: Twisted Wedge combustion chambers and intake valves moved on the opposite side of the cam. The result is dramatic increases in mid-lift airflow, piston-to-valve clearance, and valve-to-bore clearance for using higher lift cams and larger valves without altering bore size or flycutting pistons. Other exclusive features include OE PI-style intake inlets, Fast As Cast® runners that deliver near-CNC-ported airflow, CNC-profiled combustion chambers, 3/4" thick decks, patented replaceable cam bearing journals, and 3/4"-reach spark plugs. Twisted Wedge Track Heat 185 heads are intended for engines with power adders and/or high rpm applications. They fit all 2V Romeo and Windsor engines and accept all OE-style camshafts, followers, lash adjusters, valve covers, and most OE Ford front covers. The heads are available fully assembled or as bare castings. Sold individually.

Trick Flow® GenX® 280 HD Cylinder Heads for GM LS3
Trick Flow® GenX® 280 HD cylinder heads offer an unbeatable combination of performance and durability, making them the perfect upgrade for your high-performance GM LS3 engine build. Assembled with Manley Severe Duty stainless steel valves, these heavy-duty versions of the standard GenX® 280 heads can withstand the added heat, stress, and abuse dealt by big power adders. That makes them the ideal choice for engines using superchargers, turbochargers, or nitrous. GenX 280 HD cylinder heads have fully CNC-profiled combustion chambers and CNC Competition Ported square port runners with a premium high resolution surface finish that guarantees dimensional accuracy and balanced flow from port-to-port for maximum power potential. The valve angles have been modified from the stock 15° to 12° to increase piston-to-valve clearance and allow the use of larger camshafts. The coolant holes through the head decks were designed to ensure compatibility with all LS head gasket and engine block combinations. The 6-bolt-per-cylinder mounting pattern for GMPP LSX and other aftermarket blocks increases clamping force to prevent head gasket failure, cylinder distortion, and other issues that plague the factory 4-bolt design. Trick Flow® GenX® 280 HD heads have LS3 port locations to work with all LS3-style intake manifolds and LS9/LSA blower assemblies. They must be used on engines with 4.000" or larger bores. Cylinder heads are available fully assembled or as bare castings. Sold individually.
