The All-American SBF head was designed to win with state-of-the-art port and chamber technology. We have added our solid rocker boss and revised valve location for a very stable valve train. We then spent extensive time wet flow testing the combustion chamber to get the exact shape needed and a better spark plug location.

This All-American features a 205cc Intake Runner and a 63cc CNC profiled combustion chamber. We complete this powerful SBF with our 5 angle performance valve job and bowl blend.

The All-American SBF cylinder has the air speed for top speed!
