Edelbrock 77589 - Edelbrock Small Block Chevy Victor Jr. Race Series Cylinder Heads Details
Victor Jr. Aluminum Cylinder Heads
These heads have .300'' raised exhaust ports and hardened, ductile iron valve seats and phosphor bronze guides. A 9/16'' thick deck surface provides superior gasket retention. Valves are 1-piece, stainless steel. 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.
These maximum power and affordable Edelbrock Victor Jr. cylinder heads have the potential to produce 530-580 horsepower right out of the box. All heads are sold individually, and part numbers 350-77579 and 350-77649 are bare heads with valves only.
With a 12cc domed piston in a 350 engine, the compression ratio is approximately 12.5:1. In addition, these heads accept standard 23° valvetrain hardware.
