Edelbrock Cylinder Head SBC NHRA Legal 64cc Angled Plug Bare Single

Edelbrock has been a well-known name in performance parts for a long time, and their Performer RPM cylinder heads are a prime example of that legacy. This particular head, the #60947, is built for 1955-86 Small-Block Chevy engines and is NHRA legal for Stock/Super Stock classes. If you're looking to get more out of your V8, this head is designed to improve performance across a wide operating range, specifically from 1500 all the way up to 6500 rpm, giving you better throttle response and more top-end power.

What sets these heads apart is how they're made. They're cast and heat-treated right at the Edelbrock Foundry and then machined in their US facility, ensuring a well-built product. They use advanced computer technology to shape the ports and combustion chambers for improved efficiency, which translates directly to better throttle response and horsepower. You'll find solid features like threaded inserts in the rocker stud and exhaust bolt holes for extra strength, plus manganese-bronze valve guides and ductile iron valve seats – details that make a real difference in durability and performance over time.

This is a bare cylinder head, meaning it comes without valves, springs, or other valvetrain components, giving you the flexibility to choose exactly what you need for your build. The deck surfaces are thicker than many other brands, adding to the overall robustness of the head. Keep in mind that these heads are not CARB approved and cannot be shipped to California.
