Heart shaped chamber for a more efficient burn, outstanding hp and torque.

Valvetrain has been upgraded from the factory pedestal-mount system to an ARP 7/16' screw-in stud and 3/8' pushrod-slot guideplate for increased valvetrain stability.

Technical Notes: Head bolt holes drilled for stock 7/16' bolts, but can be easily modified for 1/2' bolts or studs by drilling the 1/2' counterbore. Aftermarket 7/16' stud rocker arms and 3/8' hardened pushrods required. Will fit 350-403 Olds with Edelbrock manifold p/n 350-7111 only (port matching required).
