Adjustable rockers adjusters problem?..

I can’t think of a single time the shaft needed to be lower. Ever. That would mean the valve tip is less than OE and the lift is much less than OE. So that makes zero sense.

Rocker design and tip, lift, stem height all affect geometry. If you are grinding on a rocker you have geometry issues. Fix that and leave the rockers alone.

Again, since you are carrying the flag for beehive springs (which aren’t new BTW) I’ll ask you again. How does going to a beehive spring correct bad geometry?

Looking forward to your answer.

Of course it doesn't correct geometry. The beehive springs came about when a dual spring was needed and there wasn't the room for one. At least, that's always been my understanding. I'm not sure who did it first, but I believe it was one of the foreign car companies that used a really cramped OHC head. You know, one of those where the springs are down in a HOLE in the head? lol
