Description:
These rocker stud girdles have been designed to only fit the unique geometry of the Edelbrock Big Block
Chevrolet Victor 24° head, part numbers 77409 and 77419, and the Edelbrock Big Block Chevrolet Victor Jr. 24° cylinder head,
part numbers 77459 and 77469. Made from ¾" billet, the stud girdle makes valve lash adjustments simple yet provides the
required support for high lift cams.
INSTALLATION PROCEDURE
1. After pushrods, guideplates, rocker studs, and rocker arms are properly installed, install the supplied poly lock-nuts. The
longer version nuts are for the intake rockers. Adjust each poly lock by tightening or loosening the set screw inside the
lock-nut.
2. The girdle comes in three pieces. Place the center piece between the intake and exhaust poly locks. The Edelbrock logo
should read right side up. Initially, when inserting the center piece, the grooves may not line up with the poly locks
perfectly. This does not mean you have a defective part. The reason for this is due to the compound geometry of both the
intake and exhaust rocker studs. It will take some finessing to get the center piece started, but after all poly locks are
initiated in their corresponding grooves, with a little tap or force, the whole piece should slide down to the desired location.
3. Take piece labeled "Intake" and properly line it up with the center piece. Take four supplied head cap screw bolts and
washers and bolt the two pieces together.
4. Repeat step three, but with the piece labeled "Exhaust".
5. Repeat steps 1-4 to other head.
6. Check clearances between the stud girdle and the rocker arms, as well as between the stud girdle and valve cover.
