    Pontiac Performer RPM Aluminum Cylinder Heads

    A 72cc chamber version for high-compression, racing applications. Heads have Ram Air IV exhaust port flanges. Requires head bolt kit #350-8556 for cylinder heads manufactured before 3/15/02. For cylinder heads manufactured after 3/15/02 bolt kit #350-8549 will be 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 conventional spark plugs and have a 5/8'' hex for easier access.

    These cylinder heads are designed for outstanding performance gains in 1962-79 389-455ci Pontiac engines. They are patterned after the 1969-70 Ram Air IV Pontiac cylinder head.

    Performer heads #60579/60575 are 50-state emissions legal for 1965-79 vehicles. They have 87cc combustion chambers designed to maximize performance while using less expensive, low octane fuel with a streetable 9.5:1 compression ratio.

    Performer RPM heads with 72cc combustion chamber are for higher compression engines. Performer RPM #60509 is semi-machined and must be finished by a professional head porter. They include valve guides and seats installed with no intake pushrod holes. Performer RPM #60587 is not port matched or bowl blended and is NHRA accepted for Stock and Super Stock.

    Performer RPM CNC Heads feature the same specifications as the Performer RPM heads but have CNC-machined combustion chambers, which results in a consistent and precise chamber for improved flow.
