TRICK FLOW SHALLOW CHAMBER LS2 FAST AS CAST CYLINDER HEAD BUNDLE

Trick Flow GenX 220 cylinder heads for LS 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 with port-to-valve seat blending (bowl blending), improved rocker arm/ valve cover clearance, 50° exhaust valve job, 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. Stock style powdered metal valve guides make these heads a great choice for using stock rocker arms.
