RHS® Pro Elite™ 20-Degree CNC-Ported Cast Iron Cylinder Heads for SBF

Designed with the 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 Serdi valve job for up to 5 % more airflow right from the start!
RHS® Pro Elite™ 20-Degree CNC-Ported Cast Iron Cylinder Heads for SBF Memphis, TN – RHS® introduces new cylinder heads that give Small Block Ford racers the benefits of professional CNC-porting – straight from the factory.

Featuring CNC-ported intake and exhaust runners, Pro Elite™ 20-Degree Cast Iron Heads are engineered for Ford 289, 302 and 351W circle track and drag racing applications. The 62cc combustion chambers are CNC-ported to relieve valve shrouding commonly found in “as cast” combustion chambers. To add up to 5 percent more flow right out of the box, these Pro Elite™ heads also feature hardened multi-angle intake and radiused exhaust valve seats. And prior to CNC-porting, the heads are built using RHS® exclusive Clean Cast Technology™ to provide smoother port-to-chamber transitions. The thick deck surface allows angle milling and provides increased rigidity to improve head gasket retention in boosted and nitrous applications. In addition, the refined water jacket of these heads reduces hot spots in both the engine and the cylinder heads themselves. The Pro Elite™ SBF heads feature 221cc intake runners with 79cc exhaust runners and 2.080″ intake/1.625″ exhaust valve diameters. All RHS® Pro Elite™ 20-Degree CNC-Ported Cast Iron Cylinder Heads for SBF are designed from the latest in Ford-specific airflow technology for optimal volume, atomization and velocity, giving you the power advantage at the track.
