Edelbrock 61035 Oldsmobile Roller Performer RPM Cylinder Head

The Edelbrock Performer RPM Cylinder Head for Small-Block Oldsmobile engines is designed to deliver improved airflow, horsepower, and reliability for high-performance street and strip applications. Intended for 1965-1976 Oldsmobile 350-403ci engines equipped with a hydraulic roller camshaft, these premium 356-T6 aluminum cylinder heads feature a modern 68cc combustion chamber design that helps achieve a more desirable compression ratio for small-block combinations. High-flow 200cc intake ports, 130cc exhaust ports, and optimized spark plug placement work together to enhance combustion efficiency and overall engine performance.

Engineered as a modern refinement of Edelbrock's proven Oldsmobile cylinder head design, the Performer RPM head utilizes factory 6-degree valve angles, 2.072-inch intake valves, and 1.680-inch exhaust valves to maximize airflow while maintaining OEM port locations. Additional features include provisions for a factory-style mechanical fuel pump, added material above the intake ports for future machining, Helicoil-reinforced threaded holes, and a stud-and-guideplate valvetrain system for increased durability. The assembled hydraulic roller package comes ready with premium valvetrain components for dependable performance right out of the box.
