Trick Flow GenX® 220 cylinder heads for GM 6.0L LS2 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. Trick Flow GenX 220 cylinder heads are emissions-legal under CARB E.O. #D-747 for 1997-present GM vehicles with 5.7L and 6.0L engines. They are available fully assembled or as bare castings. Sold individually.
