How far over on a 440?

Merry Christmas everyone!
I have a 67 cast date / 68 assembly date 440, Non HP. its currently .030 over. I've never ran this motor nor do I know who did the rebuild, when, and what components were used. I'm going to start tearing it down this week to see how In depth of a rebuild it needs. If it comes down to it is it safe to go .060 on the cylinders? Thanks, Dennis.
