Product Details

The Edelbrock 60559 Performer RPM Rectangle Port cylinder head is engineered specifically for Big-Block Chevy applications where serious street performance is demanded. This aluminum cylinder head delivers exceptional throttle response and power across a broad RPM range from 2500 to 7000, making it ideal for street performance builds, muscle cars, street rods, and daily drivers that need immediate seat-of-the-pants acceleration.

Key Features:

  • Rectangle port design optimized for high-performance street applications
  • Premium quality intake and exhaust valves for maximum flow and durability
  • High-performance valve springs engineered for the RPM range
  • Aluminum construction reduces weight compared to cast iron heads

Designed for use on pre-emission controlled vehicles only.
