Victor Jr. Aluminum Cylinder Heads
- Victor Jr. 20° Aluminum Cylinder Head
- Small Block Ford 289-351W
- Port Volume: 210cc/75cc
- 70cc Combustion Chambers
- Bare Head, Sold Individually
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.
