    Edelbrock 60599 - Edelbrock Pontiac Performer/Performer RPM Heads Details

    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 feature 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.
