Details Wholesale Distribution available, contact us and we can create a special listing for you! Looking for serious LS horsepower? Serious horsepower for your LS7-based engine, heads sold individually. rick 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. The cylinder heads are available fully assembled or as bare castings.
