RHS now offers a 23Ëš aluminum head for Small Block Chevy applications that is CNC-ported from the factory for precision accuracy and durability. 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. CNC-machining the combustion chamber also improves the airflow efficiency of the cylinder heads. The 2.055" multi-angle intake and 1.600" radiused exhaust valve seats allow for superior airflow, thereby significantly increasing horsepower. In addition, these 23Ëš SBC heads feature a refined water jacket for better water flow that reduces engine hot spots, while an extra-thick deck allows angle milling and improves head gasket retention in boosted and nitrous applications. RHS has designed a race-winning aluminum head that utilizes the latest in cutting-edge design technology to maximize airflow and boost horsepower in both circle track and drag racing classes.
