Just released: Trick Flow heads for the GM LS sold at Summit Racing. When it comes to the LS there are many options for horsepower. Summit Racing has them all. Trick Flow has been working hard on its GM LS GenX 260 head series. Increased strength where it’s needed, and you still can run 3/8-inch push rods. All the details are below, check it out!

Official Release:

Trick Flow doesn’t mess around when it comes to the GM LS—its GenX 260 cylinder head series is the latest salvo in the war for LS7 dominance. The heads use high flow, high velocity CNC Competition Ported runners to deliver all-out flow and performance across the entire powerband.

Trick Flow GenX 260 cylinder heads are cast from A356-T6 aluminum, beefed-up with extra material to make them rigid and strong. Factory ports, valve angles, and locations have been preserved to ensure compatibility with stock valves and pistons. There’s also plenty of clearance for 3/8 inch pushrods and through-deck coolant holes, which means they’re compatible with all GM LS gasket and block combinations. The heads feature one-piece billet aluminum rocker arm mounts to stabilize the valvetrain, yet they’re removable if builders opt for shaft rocker setups.

Engine builders can choose from fully assembled heads (with PAC Racing Pacaloy™ valve springs, retainers, locks, and valves) or bare head castings.

Trick Flow GenX 260 cylinder heads for GM LS7 were featured on Episode 4 of PowerNation’s Detroit Muscle.
