Trick Flow GenX® 220 cylinder heads for GM 5.7L LS1 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.

These heads come with stainless valves and PAC 1218 beehive springs. It also will come with hardened chromoly pushrods. If you are unsure which size pushrod you need please call. 

This package will come standard with your choice of a howards cam. We can do a custom cam from cam motion for an additional $50. If you choose the custom cam please call to discuss the details. 

Fasteners, gaskets, and lifters are offered as well in this package for an additional cost. Check below to select any parts that you wish to include in you package. 

We will supply the standard size pushrod for this cylinder head unless you call and request a different size.

All cams are for non VVT motors.
