Trickflow Genx Ls2 Bare Head Casting With Seats, 220cc Intake

Serious horsepower for your LS2-based engine, heads sold individually.

Trick Flow GenX® 220 cylinder heads for GM 5.7L LS2 engines are the best value in GM LS performance. These 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 (except porter heads) 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.
