Notes:
Designed for hydraulic roller camshafts. 75cc chambers are machined .100" for clearance with quench dome style pistons. Vacuum advance distributor may not clear cylinder head.
These Edelbrock Performer RPM aluminum cylinder heads feature threaded inserts in the rocker studs and exhaust manifold bolt holes for superior strength and durability. They also feature hardened seats, bronze valve guides, and fully machined valve cover rails for a more consistent gasket seal. They offer improved power throughout the rpm range for greater throttle response and top-end horsepower.
