Description Designed for competition big-blocks, this is a Mike Chapman CNC-ported version of the Edelbrock Performer RPM oval port head. The casting is rolled over 1�� before machining to decrease the size of the combustion chamber without shrouding the valves. Capable of 650+ horsepower on a 469-inch engine with 12.5:1 compression, this head comes with 2.25-inch intake and 1.90-inch diameter exhaust valves, both using 11/32-inch stems in Serdi-machined ductile iron seats. The high-velocity design of these heads is ideal for race and high-performance street. Sold without springs or retainers for a variety of valvetrain combos.
