Pro Elite Big Block Chevy Aluminum Heads

Increased airflow and efficiency are most essential for those drag racing and marine applications looking for the biggest possible gains in horsepower and torque. Cylinder head engineers at RHS have designed a Big Block Chevy 24-degree CNC-ported cylinder head to maximize airflow and assure port-to-port consistency in runner shapes and sizes. These BBC 24-degree aluminum heads feature multi-angle intake and radiused exhaust valve seats for up to 5% more airflow and increased horsepower. The thick deck surface of these precision-machined heads allows them to be angle milled and provides increased rigidity to improve head gasket retention in boosted and nitrous applications. The best features, however, are the CNC-ported intake and exhaust runners for optimal air volume, atomization and velocity. The RHS BBC 24-Degree CNC-Ported Aluminum Cylinder Heads are available with either a 339cc or 376cc runner volume and a 121cc combustion chamber and are designed using the RHS exclusive Clean Cast Technology to deliver superior port-to-chamber transitions for greater airflow. In addition, these heads feature a refined water jacket for more even water flow, which reduces hot spots in both the cylinder heads and the engine.

  • CNC-ported 376cc intake runners & CNC-ported 121cc combustion chambers

  • 24° aluminum cylinder heads designed for use w/ hardcore Big Block Chevy drag & marine racing applications

  • Multi-angle intake & radiused exhaust valve seats for superior airflow & increased horsepower straight from the factory

  • Extra-thick deck surface allows angle milling for compression & increased rigidity; improves head gasket retention
