Edelbrock Single Performer RPM Oldsmobile Big Block Cylinder Head (For Use w/ Hyd Roller Camshaft)

Edelbrock is well-known for its performance parts, especially for V8 engines. This Performer RPM cylinder head is designed as a direct performance upgrade for 1965-1976 Oldsmobile 400, 425, and 455 cubic inch V8 engines, particularly those using a hydraulic roller camshaft. It's a solid choice for street machines and muscle cars looking to get more out of their big-block Oldsmobile powerplants.

This aluminum head supersedes the older 60515 model and brings some notable improvements. You'll find a redesigned 77cc combustion chamber, larger intake valves, and refined bowl blending, all contributing to improved airflow. Edelbrock has also updated the intake and exhaust ports for better performance. They've even added extra material above the intake port, giving you more options for custom porting if you decide to go that route. Plus, it's designed to accommodate a factory-style mechanical fuel pump, and the spark plug locations have been slightly adjusted for better combustion.

These Performer RPM heads are cast and machined right here in the USA by Edelbrock. They come complete with high-quality intake and exhaust valves, along with valve springs, so you're getting a well-built assembly ready to go. This head fits a range of popular Oldsmobile models, including the 442, Delta 88, and Toronado, among others. Please note that this part is not CARB approved and cannot be shipped to California.
