2RZ/3RZ Cylinder Head Stage 2 2001-2004 4 Intake Ports
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 &
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
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
As with all other areas
in the valve train the area where the spring sits also takes a beating. The
spring seats will sit under the street valve spring
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 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.
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.
