    Edelbrock 605119 - Edelbrock Oldsmobile Performer RPM Heads Details

    Oldsmobile Performer RPM Aluminum Cylinder Heads

    Recommended intake gasket is Mr Gasket #720-404.
    Aftermarket 7/16'' stud rocker arms and 3/8'' hardened pushrods required.

    Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC (P/N 192-49776). They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.

    Edelbrock 605119 - Edelbrock Oldsmobile Performer RPM Heads

    Designed for high-performance non-emission 1965-76 Oldsmobile 400, 425 and 455 cubic-inch engines with Torker 455 manifold #350-2730. This head features an improved 77cc combustion chamber design that increases the quench area for a more efficient burn. This results in outstanding horsepower and torque.

    These complete heads are assembled and ready-to-run with stainless steel 2.072'' intake valves and 1.680'' exhaust valves, hardened ductile iron valve seats and phosphor bronze guides. The valvetrain has been upgraded from the factory pedestal-mount system to a 7/16'' screw-in stud and 3/8'' pushrod-slot guideplate for increased valvetrain stability.

    The high-velocity, factory location ports feature 188cc intake runners and 106cc raised-floor exhaust runners for substantially improved flow and increased power. Head bolt holes are drilled for the stock 7/16'' bolts, but can be easily modified for 1/2'' bolts or studs by drilling the 1/2'' counterbore. Aftermarket rocker arms and hardened pushrods are required for installation. These heads will fit 350-403 Oldsmobiles with Edelbrock manifold #350-7111 only (port matching required).
