Cam bearing issue

"That's why you shouldn't replace them unless you absolutely must.[/QUOTE]

That's just silly advice unless your building garbage. Anytime I take a block in, it's tanked, magged and gets new cam bearings. Never had an issue in my 30 years of screwing with cars. If the cams tight and you're not comfortable re-sizing, just have the shop do it. Better yet, before you pickup your block, give them your cam like I do, and it'll be ready to go once you wash it up.
