    Victor Jr. Aluminum Cylinder Heads

    With 500+ HP potential out-of-the-box, these heads have the same competition proven features as the Victor Jr. Ford heads but with 70cc combustion chambers. The 70cc combustion chambers are ideal for turbocharged and supercharged applications that require a lower staic compression ratio. Other feautre include CNC gasket-matched port entries and exits with blended valve bowls. The spark plug holes and valves are in the stock location with .150'' raised valve cover rail. A groove in the deck surface allows most roller lifters to be changed without removing the heads.

    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 a conventional spark plug and have a 5/8'' hex for easier access.

    Victor Jr. Series Heads are perfect for OE-Performance engines with stock valve train and pistons for bolt-on performance. Available as a complete head which includes valves, springs & retainers or as a bare head so the valve springs can be matched with recommendations from the camshaft manufacturer.

    Victor & Victor CNC Series Heads are designed for use in racing applications. Some of the best racers in the country rely on Edelbrock's Victor and Victor CNC series heads to help them win the race. These heads feature raised runners, revised combustion chambers and relocated valves for all-out performance in competition engines.
