SBM Performer RPM Cylinder Head - Bare

The SBM Performer RPM Cylinder Head - Bare is an aluminum casting specifically designed for Small Block Mopar engine builds. This performance head is ideal for both carbureted and fuel-injected applications, where optimizing intake velocity and cylinder filling efficiency is crucial for enhancing horsepower across the RPM range.

Featuring 2.020-inch intake valves and 1.600-inch exhaust valves, the head has a 171 cc intake runner volume and a 63 cc combustion chamber. Its angle-plug design allows for an optimal spark plug position, promoting better flame propagation and combustion efficiency. As a bare casting, it requires final valve seating and port work, giving builders the flexibility to customize it for their specific fuel delivery and ignition systems.

Engine builders and performance enthusiasts working on Small Block Mopar platforms, such as the 318, 340, or 360 cubic inch variants, will find the Performer RPM head beneficial for maximizing intake efficiency. This head is suitable for both street and race applications, allowing for a balance between low-end torque and mid-range power delivery.
