Trick Flow GenX® 220 cylinder heads for GM 5.7L LS1 engines are a great value in GM LS performance. The cathedral port heads incorporate features of Trick Flow’s fully CNC-ported LS heads 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.

Other features include shallower 13.5° valve angles to decrease valve shrouding and increase 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 a rigid casting design. The Trick Flow GenX 220 LS1 cylinder heads are available fully assembled or as bare castings.
