Pro Elite Small Block Ford 289-351c.i. Aluminum Heads

Designed with Small Block Ford racing enthusiast in mind, these heads give you all of the benefits of professional CNC porting straight from the factory! However, the CNC porting is done off of a known port, providing more airflow consistency than hand-ported runners. In addition to the CNC-ported intake and exhaust runners, the combustion chambers are also CNC-ported to moderate valve shrouding and maximize airflow efficiency. Prior to porting, the heads are given a multi-angle valve job for up to 5% more airflow right from the start!

  • Designed for Small Block Ford 289, 302 & 351W drag & circle track racing applications

  • CNC-ported 62cc combustion chamber moderates valve shrouding & improves airflow efficiency

  • Thick deck surface allows angle milling & increases rigidity; Improves head gasket retention

  • Multi-angle intake & radiused exhaust seats for superior flow & increased horsepower

Some parts are not legal for use in California or other states with similar laws/regulations
