Serious horsepower for your LS3-based engine, heads sold individually.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. The cylinder heads are available fully assembled or as bare castings.Manufacturer’s Part Number: TFS-3271B001-C01Part Type: Cylinder HeadsProduct Line: Trick Flow® GenX® 260 Cylinder Heads for GM LS7UPC: 842645109140Cylinder Head Style: BareCylinder Head Material: AluminumCylinder Head Finish: NaturalCombustion Chamber Volume (cc): 70CNC-Machined Combustion Chamber: YesIntake Runner Volume (cc): 260ccExhaust Runner Volume (cc): 87ccCNC-Machined Intake Runner: YesCNC-Machined Exhaust Runner: YesCombustion Chamber Style: HeartIntake Port Location: StandardExhaust Port Shape: OvalExhaust Port Location: StandardIntake Valves Included: NoIntake Valve Diameter (in): 2.200 in.Exhaust Valves Included: NoExhaust Valve Diameter (in): 1.600 in.Valve Springs Included: NoDamper Spring Included: NoRetainers Included: NoLocks Included: NoValve Stem Seals Included: NoRocker Arm Studs Included: NoRocker Arms Included: NoRocker Arm Nuts Included: NoGuideplates Included: NoAccessory Bolt Holes Drilled: YesIntake Valve Angle: 12Exhaust Valve Angle: 12Valve Guides Included: YesValve Guide Material: Powdered metalValve Seats Machined: YesValve Seat Machine Style: 3-angleValve Seat Material: Ductile ironSteam Holes Drilled: NoOiling Style: Through pushrodMachined for O-Ring: NoHeat Crossover: NoQuantity: Sold individually.Notes: These cylinder heads are not designed as a stock replacement, they can only be used on 6 bolt LSX-based engines with a minimum bore diameter of 4.000 in.
