We have a KB block with the bores at 4.530", would it be safe to go say another .010" assuming a ring is available.
12.5-1 NA.

10 off is only .005" per side, but if your doing this just for power and not repair and you can't find a drop in ring that would only need a max of .003" of filing then your building a compression leaker from oval rings!

Total seal will make you any size ring you want.
