So to the original question can you tell if a block is any good before you take it to a machine shop. The answer is NO. All you can do is determine it's bad.
So don't pay more than scrap price until you know it's good

I absolutely misinterpreted your post, my mistake.

You are correct, figure out if it's worth buying, then get it to a machine shop and start saving your pennys.
