Head Porting

The art of head porting is designed to make your engine function with less work. The idea is to allow air and fuel in and exhaust out with a higher level of efficiency. All of our porting here at RPM starts with a valve job and making sure all your valve seats are cut correctly for optimum flow characteristics. If your engine can breath easier, then your engine can turn that into power.

Porting heads correctly also involved making sure the porting is done to match the other components that are going into your engine.

Street Port: Starts with a valve job. Then valve seats are blended into the heads. Minor pocket porting is done behind the valves and into the head. Focusing on the short side radius of both the intake and the exhaust ports.

Performance Port: Services above plus also blending the pockets into the runners of both exhaust and intake. Performance porting can also sometimes include blueprinting of the intake manifold to match.

Race Port: Above services plus full and complete porting and polishing of all runners in the heads. Both intake and exhaust and worked from entry to exit. Special attention is paid to all mating surfaces to be sure everything is lined up correctly.
