    Engineers at RHS have recently designed a 23 degree aluminum head for Small Block Chevy applications that is CNC ported from the factory. The precision accuracy and durability of the new RHS Pro Elite 23 Degree CNC Ported Aluminum Cylinder Heads for Small Block Chevy 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.

    Key Features:

  • CNC ported 228cc intake & 82cc exhaust runners
  • The 2.055" multi-angle intake & 1.600" radius exhaust seats allow for superior airflow for more power
  • CNC ported 69cc combustion chamber relieves valve shrouding & improves airflow efficiency
  • Clean Cast Technology delivers superior port to chamber transitions for greater airflow
