Edelbrock 61039 Performer RPM Olds Flat Tappet Cylinder Head

The Edelbrock Performer RPM Cylinder Head for Small-Block Oldsmobile engines is engineered to provide increased airflow, horsepower, and reliability for high-performance street and strip builds using a flat tappet camshaft. Designed for 1965-1976 Oldsmobile 350-403ci engines, these 356-T6 aluminum cylinder heads feature modern 68cc combustion chambers that help achieve a more desirable compression ratio for small-block applications. High-flow 200cc intake ports, 130cc exhaust ports, and optimized spark plug placement work together to improve airflow efficiency and combustion performance.

These Performer RPM heads are a refined evolution of Edelbrock's proven Oldsmobile cylinder head design, offering factory port locations, a factory 6-degree valve angle, and compatibility with a factory-style mechanical fuel pump. Large 2.072-inch intake valves and 1.680-inch exhaust valves maximize airflow, while reinforced features such as Helicoil inserts, added material above the intake ports, and a stud-and-guideplate valvetrain system provide improved durability for demanding performance applications. Fully assembled and ready for flat tappet camshaft combinations, these heads deliver modern performance while maintaining excellent compatibility with OEM and aftermarket components.
