I'm 100% with Jerry on this. I've bought engines like that...block and heads that were "rebuilt" only to find stuff didn't even get close to the right tolerances. And I mean terribly off. In fact the 235 I have now was in that condition when I got it. Example: Ring end gap ranged from .035" to .045". GM specs? .007" to .020". And that's just the first thing I noticed. At least back then you weren't spending an arm and leg. Today things are different. Good luck!
