Trick Flow® GenX™ 220 Cylinder Heads for GM LS2

Fast as cast!

If you're looking for the best value in GM LSX performance, look no further than Trick Flow's GenX 220 aluminum cylinder heads with Fast As Cast runners.
These GenX 220 heads feature all of the same goodies that make our CNC-ported heads so incredible—13.5 degree valve angles, decreased valve shrouding, increased midlift airflow, relocated spark plugs, improved rocker arm-to-valve cover clearance, and rigid casting design for extreme horsepower applications—but in a more affordable cast version that flows nearly as much air as the CNC-ported heads. The Trick Flow GenX 220 performance cylinder heads come with 220cc intake
and 80cc exhaust Fast As Cast runners that duplicate the port shape and profile of full CNC-ported runners. The result is near CNC-ported power and performance for the same price as ordinary cast cylinder heads. Combustion chambers are 65cc and valve sizes are 2.055 in. intake and 1.575 in. exhaust. Other features include bronze valve guides, ductile iron intake and exhaust valve seat inserts, 1.300 in. dual valve springs, Viton® fluoroelastomer canister-style valve seals, 7 degree machined steel valve locks, and 7 degree titanium retainers. Bare cylinder head castings are also available.
