Pro Elite Aluminum 23-Degree SBC Cylinder Heads

RHS Pro Elite 23-Degree Aluminum Cylinder Heads for SBC applications feature precision CNC-ported intake and exhaust runners, as well as combustion chambers for maximum airflow and cooler operating temperatures in circle track and drag racing applications. These revolutionary cylinder heads are designed using exclusive Clean Cast Technology to deliver superior port-to-chamber transitions for greater airflow. The CNC-ported 228cc intake and 82cc exhaust runners optimize volume, atomization and velocity, while the 69cc combustion chambers are CNC-ported to relieve valve shrouding that occurs in "as cast" chambers when the edge of a valve is in close proximity to the combustion chamber wall. These race-winning aluminum cylinder heads are available bare or fully assembled with premium-quality COMP Cams valve train components.
