Thanks spannerman for your informed (and independent) post, that is just what we needed here

So in conclusion, learned/observed FACT:- gaps do ALL close (unless there is something wrong), also Kawasaki suggested at one point shimming to the larger end of tolerance for this reason.

So back to where we came in, to me if you are buying shims and taking on this (not the most pleasant) job; then why not shim on the bigger gap side of tolerance to increase interval where it needs to be done again??? To my mind, the only time it is worth shimming close is if it is a race engine, where every fraction of a HP maters (that little bit more lift) and where it is in bits so often anyway!!!!!
