Default HELP! removed coolant plug striped threads.

I didn't but my builder did he was removing the plug..didn't use heat! So it got tight and once out he found pulled threads in the block. He was going to put in a block plug,

Options to close the hole?

Thanks.

I'd whittle down a scrap of 1/8" or 3/16" and TIG weld a plug in the hole.

Engine is installed so to Tig would need to remove.
He says he can get in to retap without removing so guess we try that first worst case remove engine and tig.
Kids...have to teach them everything. He's extremely talented but still young so can't get to mad their are things he hasn't learned..lesson learned now.
