Is this a good deal for a 340?

Honestly if I could choose I'd get a block that hasn't been bored at all. Is there any problem with the block already being machined to 40 over? I'm not looking to go any bigger or get huge HP gains but I will admit I don't know the cons of it already being 40 over. I took a look at it for a little bit and it looked newly machined but like I told him, I could be looking at a chevy 327 and not know the difference :banghead:
