Fred,
I guess this isn't the answer you want but the usual approach is to do a compression test dry (which it sounds like you did) and then squirt a little bit of 30W oil into each spark plug hole as you repeat the compression test. With good rings and bores the figures won't hardly rise at all but with worn rings the figures will skyrocket as the oil momentarily helps the rings seal. Have you check that the head is really flat?
