RHS Introduces New Iron Cylinder Heads


Engineers at RHS have recently designed the only Small Block Chevy 23-degree cast iron head that is CNC-ported from the factory. The precision accuracy and durability of the RHS Pro Elite SBC 23-Degree CNC-Ported Iron Cylinder Heads are derived not only from the precision CNC-porting of the intake and exhaust runners but the CNC-ported combustion chamber, as well.

 

The 2.055” multi angle intake and 1.600” radiused exhaust valve seats allow for superior airflow, thereby significantly increasing horsepower. In addition, these 23-degree SBC heads feature a refined water jacket for more even water flow to reduce engine “hot spots” and an extra-thick deck to allow angle milling. The thick deck surface also improves head gasket retention in boosted and nitrous applications. For racing classes that mandate cast iron head use, RHS has designed a race-winning cast iron head that utilizes the latest in cylinder head technology.
