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.
