Re: valve job?
I agree with the compression test, you probably won't sleep nights until you do it. As long as all holes are fairly close to each other, you're fine. If the engine is old and tired then I wouldn't worry much about total readings, just how close each is to each other.
Removing the side cover [ manifolds don't have to come off] and checking for some lash isn't a bad thing to do. If its been that long since a rebuild, or never having a rebuild, then it just may have non adjustable lifters. So any lash at least .010" on intakes and about .013" on exhaust should be fine.
