Edelbrock 60579 - Edelbrock Pontiac 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 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.
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.
Patterned after the 1969-70 Ram Air IV Pontiac cylinder heads, these heads produce outstanding horsepower with excellent low-speed torque and throttle response.
