Big-block Chevy engines are the weapon of choice for the majority of fast sportsman drag racers out there. Yes, all three makes are represented in some form, but walk though the staging lanes at an event where Super Comp, Top Dragster, Top Sportsman, or any other class where big snot is necessary and you’ll be swimming in Bow Ties.
One of the reasons for that is the readily available selection of hardcore speed parts like these new cylinder heads from RHS. Insane power is at your finger tips, or more accurately, the end of your credit card.
Read up on these new 24 degree offerings from RHS and commence drooling.
RHS™ Pro Elite™ BBC 24-Degree CNC-Ported Aluminum Cylinder Heads
Increased airflow and efficiency are 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.
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 combustion chambers are also 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. The RHS™ Pro Elite™ 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.
