|RHS® Pro Elite™ 23-Degree CNC-Ported Aluminum Cylinder Heads for SBC
Memphis, TN – New Small Block Chevy 228cc runner heads from RHS® provide maximum airflow and cooler operating temperatures in circle track and drag racing applications.
Engineers at RHS® have recently designed a 23-degree aluminum head for Small Block Chevy applications that is CNCported from the factory. The precision accuracy and durability of the new RHS® Pro Elite™ 23-Degree CNC-Ported Aluminum Cylinder Heads for SBC are derived from the precision CNC-porting of the intake and exhaust runners, as well as the combustion chamber. These revolutionary cylinder heads are designed using the RHS® 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. 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 23-degree 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.
Founded in 1967, Racing Head Service® began exclusively as a manufacturer of racing cylinder heads. Over the years, RHS® grew into an integrated racing company, offering complete turn-key engines and race car parts via mail order.
