Trick Flow GenX 220 Assembled Cylinder Head, Cathedral Port LS1, LS2 Each

Trick Flow GenX 220 cylinder heads for GM 6.0L LS2 engines are the best value in GM LS performance. The cathedral port heads incorporate features of Trick Flow’s fully CNC-ported LS heads such as 13.5° valve angles, decreased valve shrouding, increased mid-lift airflow, relocated spark plugs, CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending), improved rocker arm/ valve cover clearance, and rigid casting design in a more affordable “Fast As Cast” version that flows nearly as much air as Trick Flow’s competition ported heads. The special Fast As Cast runner design duplicates the port shape and profile of fully CNC-ported runners, resulting in near-CNC-ported performance for the same price as regular cast cylinder heads. Cylinder heads are available fully assembled or as bare castings.
