Building the Pure Stock engine replaced the 3/8 with a 7/16th stud figuring it was a good bit stronger. Cannot remember the racers name he sent me his modified LT1 SA Stock Rockers. Bought new 7/16th ball, installed them and runs smooth.

Like Billy said, he saw no gain going to Rollers.

Many of our Impala Club members stayed with the Stock LT1 SA rockers installing the popular HotCam with no problems. Figuring the 3/8th Stud was not much of an issue to begin with.

Wondering if someone makes a 1.5 SA Roller Tip?
Use the 7/16th ball and trim the sides up to fit.
Would stop all side loading on the valve and guide.

I have set of original GM SA 1.6 Roller Rockers.
Then again they use 3/8 stud.
Saving them for a project.
