I notice the bidding is going slow on this. Not surprising, it is my opinion that if you want to know what you have you do it yourself, and if you want to buy a rebuilt engine, you expect to pay a lot less than the cost of rebuilding it yourself unless it is done by a professional and comes with a warranty. Too much "buyer beware" out there. This one looks really good and the guy sounds like he's pretty straight up, but how do we know he didn't try to weld a crack in the block or something, or just not know the proper way to torque the head?
