Trickflow GenX LS3 280cc Intake, 6-Bolt Aluminum Cylinder Head - Boost Ready

Trickflow is building on the features that make the GenX 255 for GM LS3 great—like 12 valve angles and relocated valves for reduced valve shrouding and improved piston-to-valve clearance—Trick Flow's GenX 280 HIP cylinder head withstands the abuse of high horsepower, power-adder performance demanded by today's racers and engine builders.

The GenX 280cc heads list of features is long, and it starts with the HIP'd (Hot Isostatic Pressed) castings. This process significantly increases the casting's density for improved tensile and fatigue strength. It continues with industry leading airflow through CNC Competition Ported 280cc intake ports and Trick-Alloy powdered metal valve guides for added longevity. Manley Severe Duty intake valves and Extreme Duty Inconel exhaust valves are designed to withstand the abuse of extreme temperatures and stresses of big power adder applications. Trick Flow by PAC Racing dual valve springs, titanium retainers, .750-inch thick deck, and 6-bolt-per-cylinder mounting pattern round out the features.

This Trick Flow GenX 280 HIP cylinder head work with all LS3 intake manifolds and LS9/LSA blower assemblies and fit all LS head gasket and engine block combinations. Sold individually.
