Stryker Cylinder Heads

VIPER CYLINDER HEADS- Forget about falling into the C.F.M. flow bench numbers game; We are talking about POWER here.. 

For the Gen I, II, 3 and Gen 4 engines, we offer CNC-Ported O.E.M. (stock castings) heads that are completely race ported with high grade components installed and ready to bolt-on with ported intake manifold and custom camshaft. Approx. power increases over stock: Dyno's from our customers have proven over 115+ RWHP gains.

 STRIKER CYLINDER HEADS NOW !

 We are now offering THE ONLY Aftermarket Cylinder Head Available for the Gen II and Gen III Viper engines, we have the original Striker S and R series Cylinder Heads. 

These heads are a completely revamped design and fly past the limitations of the original O.E.M. design in both in power and efficiency. Utilizing the latest in CNC technology, these heads have a completely new "fast-burn" combustion chamber, revised Intake Guide/Valve and plug location, superior coolant passages (noticeably cooler engine operation), robust valve train pads and a thick deck so these heads can really take a pounding. They come complete with a custom Jesel roller rocker system, Ferrea stainless valves, valve springs matched to your camshaft, titanium retainers, hardened keepers and new seals.
