    Edelbrock 60579 - Edelbrock Pontiac Performer/Performer RPM Heads Details

    Pontiac Performer Aluminum Cylinder Heads

    Street legal 87cc combustion chamber version for low-compression applications using 92 octane fuel. Heads have Ram Air IV exhaust port flanges. The 87cc combustion chamber has been designed to maximize combustion efficiency with streetable compression ratios such as 9.5:1.

    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.

    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.
