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.

Dan…PRW make 1.5 x 7/16 Self Aligning roller tip rockers. Part number is PRW 0835920. If you already have converted to 7/16 studs, why don't you just buy the proper guide plates and a decent set of Roller Rockers and be done with it. Eventually you will end up there anyways. Hope this helps. MB
