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 cylinder heads withstand the abuse of high horsepower, power-adder performance demanded by today's racers and engine builders. The GenX® 280 heads list of features is long, and it starts with your choice of a HIP'd (Hot Isostatic Pressed) or standard casting. 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 your choice of Extreme Duty Inconel or Severe Duty Stainless Steel 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. Trick Flow® GenX® 280 cylinder heads for GM LS3 work with all LS3 intake manifolds and LS9/LSA blower assemblies and fit all LS head gasket and engine block combinations. These cylinder heads are available fully assembled or as bare castings. Sold individually. Key features: * 280cc intake ports and 67cc combustion chambers * Choice of HIP'd or standard casting * Accepts 3/8 in. pushrods * Powdered metal valve guides * 2.165 in. NK-844 severe duty stainless steel intake valves * 1.600 in. extreme duty Inconel or severe duty stainless steel exhaust valves * .750 in. thick deck * 6-bolt configuration * Assembled heads include a Trick Flow® LS3 rocker stand
