Description Ideal for racers looking for an affordable head that makes maximum power, the Victor jr. 23� heads are designed for competition and ultra high-performance street small-blocks and accept standard valvetrain hardware. They have a 530-580 horsepower potential, out-of-the-box, for a cost effective, race-winning setup. Combustion chamber sizes include 70cc or the 64cc version that is ideal for entry-level racers or high-end street. The 64cc combustion chamber yields around 10:2:1 compression in a zero-deck flat-top 350-inch engine, and about 12:5:1 when used with a 12cc domed piston. Both versions of the Victor Jr. 23� head high-flow 215cc intake ports with CNC port-matched entries, .300-inch raised exhaust ports, hardened, ductile iron valve seats and phosphor bronze guides. A 9/16-inch thick deck surface provides superior gasket retention.
