RHS® Pro Action™ SBC 23-Degree Style Raised Runner Cylinder Heads

New cylinder head styles from RHS® feature 220cc runner volumes and are available in either “as cast” or P-Port configurations

Finding a top performing cylinder head and still staying within the rules of class competition may be one of the biggest challenges engine builders face today. The RHS® Pro Action™ Small Block Chevrolet 23-Degree Style Raised Runner Cylinder Heads incorporating the “as cast” 220cc runner volume were originally designed for circle track competition, but these are also the “winning ticket” for Nostalgia Drags Junior Class B Fuel competition.

The RHS® Pro Action™ SBC 23-Degree Style Raised Runner Heads are cast iron heads that have been angle milled from the factory to 21-degrees, which significantly improves the performance potential of the head. This cost saving modification is acceptable by most race sanctioning bodies and allows a two-degree plus or minus valve angle change from the stock Small Block Chevy placement. In addition, these heads are available in P-Port versions, which feature added material in all the critical areas so that customers can port the heads to meet their specific requirements. The RHS® Pro Action™ 23-Degree Style Raised Runner Heads are available in three configurations, including the standard “as cast” version with 220cc intake runner port volumes, raised runner P-Ports with seats and guide holes machined and raised runner P-Ports without machined seats or guide holes.
