2RZ/3RZ Cylinder Head Stage 2 1996-2000 8 Intake Ports
LC Engineering has the best upgrades for the dual over head cam 2RZ/3RZ engine. This Cylinder head will supply you with a better than stock head to upgrade 2RZ/3RZ performance engines. This is an excellent cylinder head choice to upgrade with our Stage 1 or 2 camshafts.
This cylinder head comes fully assembled with a high performance 3 angle valve job. Parts required for install that are NOT included, are Camshafts and OE buckets. Shims will be required. The head must be torqued onto the engine block in order to perform this step.
Cylinder Head Casting
We have seen all the import head castings the only one that is worth using is the OEM Toyota head casting. While this head casting is more than 3 times the amount of the imported one this is the only one that has the quality to give years of service.
Stainless Steel Intake & Exhaust Valves
These Stainless Steel valves are stock sized exhaust valves 30.5 mm, intake valves 37.5 mm, great for ported street heads that don't need the huge oversized valves. These stainless steel valves are lighter than the stock steel valves, and have a special anti-friction coating to promote better airflow across the valve as well as reduced resistance in the guide, resulting in better valve train stability.
Street Valve Springs
LC Street springs offer a higher spring pressure than your stock springs. The raised spring pressure will allow your engine to rev faster and higher than with stock springs. Stock spring 35 lbs. at lift of .320 70 lbs. LCE Street spring 50 lbs. at lift of .320 118 lbs.
Toyota Spring Seats
As with all other areas in the valve train the area where the spring sits also takes a beating. The OE spring seats will sit under the street valve spring and will hold up to the extreme pressures and higher RPM'S found in performance engines.
LCE uses the Toyota Retainer as it fits our Street Springs perfect. There is no need for light weight or exotic materials.
Hardened Valve Keepers fit all 6mm valves using stock Toyota retainers.
Viton Valve Seals
Viton Valve Seals are the latest in valve seal material, surpassing Teflon! Heat resistant to 440 degrees, they eliminate oil consumption through the valve guide and provide smoother engine idling by stopping manifold air and oil leakage past the seal. They insure a perfect seal for maximum performance and long engine life.
LCE has the experience necessary to port the cylinder heads for the utmost in efficiency. The Stage 2 porting will clean up casting inconsistencies while increasing the flow characteristics of both the exhaust and intake ports. The cylinder heads will also go though a complete deburring process.
