Performer RPM Aluminum Cylinder Heads - Rectangle Port
Tech Note: The Spark plug is closer to center of bore, for use with flat top or low dome pistons and will interfere with high-dome pistons for open chamber heads. If a high compression domed piston is to be used, purchase a piston designed for use with this Edelbrock cylinder head.
Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC. They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.
