Doesn't look good to me.. Can't really see what the internal part is.. a thread bold or something?
do you have the chipped part.. if so.. maybe have welded back on to repair.. but I'd junk the block if it was me.. knowing that it touched some internal parts.. I would expect it to be critical that it be strong and precise on it machining.

No! That's the funny part, motor never had been taken apart, he was the only one to take the heads off...and that kind of damage wouldn't happen from just removing a head.....so i'm confused.

If that is a head bolt thread, I would be concerned about the clamping load of that bolt. If you are going to JB weld it - I'd use studs and then JB it after the stud was in. Might not matter, just what I'd do for insurance...

What likely happened is fluid (coolant,oil,etc) manages to get down in the hole and if they dont get blown out with compressed air before reassembly..POP..the hydraulic pressure cracks the block. There are many instances of this.
