Friend had the same issue a couple years ago. I suggested he build it up and see how much it moved in the wrong direction. What he found out was that when he built it up 1/4" it moved about three to four inches. So he looked at shaving it down 1/4" and decided not to do it. It would have cupped it out. The height was fine and he might even had ended up with a lower comb he figured. Had it been too high he might have tried it. So down the road that gun went but at least it was unmolested. Too many are not.
