Performer RPM Small-Block Chevy
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 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.

E-Street™ cylinder heads are an all new line of Edelbrock heads designed for entry-level street performance engines, ideal for operating in the idle to 5,500 rpm range. Manufactured in the USA, by Edelbrock, these heads feature A356 aluminum castings that are heat treated to T-6 spec for superior casting strength and quality. Their modern combustion chamber designs improve the combustion process and larger than stock intake and exhaust ports move more air through your engine. These features improve an engine's efficiency, resulting in more horsepower and torque and improved mileage potential. Dyno tests showed a gain of 16 hp and 11 ft/lbs of torque over our overseas competitor.

Every E-Street is assembled with manganese bronze valve guides, powder metal interlocking valve seats, stainless steel one-piece valves with hardened tips, 1.25" diameter valve springs, 3/8" screw-in studs and guide plates. Additional qualities include hardened spring cups for long-term wear protection and Heli-coil™ threaded inserts in the rocker stud bosses for increased strength; these are the details that most low-cost competitors leave out of their heads. All E-Street cylinder heads are sold in pairs and Made in the USA.
