350Z Stage 2 Cylinder Heads

Stage 2 heads feature extensive port work on the intake and exhaust. We utilize stock valves and springs which are inspected and tested to meet factory specifications. The heads get surfaced to insure straightness. New guides and seals are installed and the valves and seats get a 3 angle grind and are lapped before final assembly.

Stage 2 heads also feature a JWT valve spring and titanium retainer package is used to replace the stock springs and retainers.  This allows for higher rpms without the risk of valve float at high rpms.  These heads are capable of 7500 rpms.
