The Performer RPM Cylinder Heads by Edelbrock are ideal for street, drag racing, and marine applications.
These cylinder heads offer increases in horsepower, throttle response, and torque throughout the RPM range that are dyno-proven.
They feature top quality elements such as threaded inserts for rocker studs and exhaust manifold bolt holes for durability and strength, along with manganese-bronze valve guides.
The CNC-profiled intake and exhaust runners ensure superior flow and performance.
These heads produced over 500 hp at 6,500 RPM (+30 hp more than ported factory heads) and 525 foot per pounds of torque at 4,500 RPM with the Performer RPM Total Power Package.
A 75cc combustion chamber is available to provide a variety of compression ratio choices with different engine sizes.
They accept factory exhaust, aftermarket headers, and factory valve train components, requiring the use of 3/8" diameter pushrods.
