Tim-
1- Wait till the #'s come in on your latest block - - and I know how hard it is to wait. Over 7months for me now
2- if it can go .030 or .040" then you know what to do
3- if it's no good (that one cyl didn't look great) you can go 60 over on the one you've had forever but like we talked about- you should have it sonic checked if you do.
4- sip some of that good brew you picked up yesterday

and wait to hear about the new found block. Then go with #3 or you are looking at a different block. My 418 just sold or I'd offer it to ya.
5- none of those optios work? Look for another block. Like someone said, newer blocks at 200K miles are better than most non-metric ringed early builds at 20k miles
