NOTE: The 302-351 Race Heads are for engine applications that are in need of high port volume/C.F.M.
These heads flow between 350-445 C.F.M. (on a certified super flow 1020). The 4.30 Cylinder Head is designed to be C&C ported, and flow as much as 445 C.F.M. on a Certified Super-Flow 1020 after C&C porting.
