I have seen all kinds of motors especially chevys. I have sonic checked and magged alot also. To tell you the truth it doesnt matter when it was made. Seen the early ones 010 020 crack and be thin between the cylinders. Now dont get me wrong I would take a 70 motor over an 80s-90s block anyday. 010 have the better nickle content. The later motors were getting cheap and thin. So what would I do? I would find out which is a 4 bolt. Then I would find out if the been rebuilt before. Then I would pick one and take it in and have it cleaned, magged and sonic checked. Chevys I have noticed are thin between the cylinders. Cause for an over heating problem. Post some pics of the valleys of the motors. Maybe we can see somthing before you go thru the trouble.
