New set of 7/16" Pioneer screw-in rocker arm studs, these are a good upgrade from the weak stock 3/8" bottle-neck screw-in studs. These are big-block Chevy-style studs with 7/16-14 bottom threads and 7/16-20 top threads, they are a direct bolt-in on Pontiac heads that already have factory screw-in rocker studs. Add a set of self-locking big-block Chevy rocker nuts and you will have a more durable (and now adjustable) valvetrain than stock for a low cost.
From the bottom of the hex to the top of the stud they measure 1.785", from the bottom of the hex to the bottom of the stud .750".
