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!
