I found the studs in a Mr.Gasket online catalog. Wish I knew how to work with that stupid Adobe stuff so I could post a picture. Anyways here is what is written along side the picture:

SCREW-IN ROCKER ARM STUDS
Made from alloy steel, this stud is ideal for use with hi-performance cams in cars used primarily on the street. The studs are concentric to keep the rockers, push-rod and valve stems in alignment. No jam nut is required. Simply tap the boss and screw in the studs. Fits Chevrolet 283 thru 400 and Ford with a 7/16"-14 threaded hole in head. Use 3/8" Sure-Lock rocker arm adjusters. 7/16"-14 tap required. Set of 16 without oil hole, 2-5/16" long.................................... 1076
