Valve adjustment question - loosening and tightening?

My experience has always been with tighter valves when I had the gpz.  Never had to go up a size in shim, always down.

Keep in mind in the gpz valve train, you got cams and rocker arms that can wear.  If that's the case in your situation, I can see the clearances enlarging.  Odd, but possible.
