Technical Specs
Designed for 302, 327, 350 and 400 cid small-block Chevy engines up to 1986, these Performer RPM cylinder heads are available fully assembled and ready to bolt on or bare for use with your own valve train components. Features include high-quality stainless steel 2.02" intake and 1.60" exhaust valves, choice of 64cc or 70cc combustion chambers and high flow 185cc intake and 65cc exhaust ports. Intake and exhaust runners are hand blended in the bowl area and the intake entries and exhaust exits are cnc profiled for increased air-flow. These heads include adjustable rocker stud and guide plate set-up for use with adjustable rockers. The casting is manufactured of virgin A356 aluminum and heat treated to T6 spec for superior quality. An extra-thick 5/8" deck and Heli-coil threaded inserts offer improved durability. Performer RPM cylinder heads are available with straight or angled spark plug configuration to fit a variety of exhaust applications. Made in USA.
