GenX® 260 square port LS7 aluminum cylinder heads from Trick Flow® are the best choice for your LS-based performance build for several reasons. The A356-T6 aluminum castings feature more material for increased rigidity and strength. Factory LS7 port locations, valve angles, and valve locations have been maintained to work with existing intakes and pistons. One-piece modular, 2024-T4 billet aluminum rocker arm mounts enhance valvetrain stability and are removable for shaft rocker setups. 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. Plus there’s clearance for 3/8″ pushrods and through-deck coolant holes that fit all GM LS gasket and block combinations, Trick-Alloy powdered-metal valve guides, and solid stem valves. Fully assembled heads also include Trick Flow® by PAC Racing Pacaloy™ valve springs, steel or titanium spring retainers, die forged steel valve locks, and stainless steel valves.
