7/16” Straight Rocker Studs & Guide Plates
New set of Pioneer or Elgin brand aftermarket 7/16” screw-in rocker studs with good used OEM Pontiac 5/16” guide plates. The studs have 7/16-14 UNC bottom and 7/16-20 UNF top threads.
Overall length is 2.510” and 1.705” from the base of the hex to the top, the tops have been turned in a lathe to provide a flat surface for proper seating of polylock locking set screws.
These studs are a nice inexpensive bolt-on upgrade over the failure-prone factory bottle neck screw-in studs. Can be used with either 7/16” polylocks or BB Chevy crimp nuts. This gives you an adjustable valvetrain which is much better than the Pontiac factory setup.
