Racing Head Service (RHS) 23-Degree Aluminum Cylinder Head

Racing Head Service’s (RHS) 23-degree aluminum cylinder heads are CNC-ported from the factory to ensure precision accuracy and durability. The 228cc intake and 82cc exhaust runners are able to optimize volume, atomization and velocity, while the 69cc combustion chambers are also CNC-ported to relieve valve shrouding. The heads feature Clean Cast Technology that delivers superior port-to-chamber transitions for greater airflow efficiency. They are now available for Small Block Chevrolet applications.
