Isky Rocker Problem

I just read on another site that Isky used to recommend that you grind down the tabs on the hold downs. That would put them in the correct spot. I did just notice while playing around with them that the springs create quite a bit of drag on the rockers, I will ditch them and go with the spacers I have which consist of rubber O rings and metal shims.

These rockers are already galled, but not terribly. I picked the best out of a box of 32 and some of them are perfectly fine. Do you mean a 3/8" long banana groove or 3/8" from the oiling holes ?
