Notes:Heads are designed for use with a hydraulic roller camshaft. Head bolt holes drilled for stock 7/16 in. bolts, but can be easily modified for 1/2 in. bolts or studs by drilling the 1/2 in. counterbore. Aftermarket 7/16 in. stud rocker arms and 3/8 in. hardened pushrods required. Heads used in S/B applications require the use of EDL-7111 Performer RPM manifold exclusively, and port matching will be required for installation.
