Drain plug thread repair
I think I managed to save my block by removing a broken easy out from the coolant passage drain plug. I had to drill a small relief hole to accomplish this which cut into the threads a bit. Looking for options to best address this... I figure I have three or four solid approaches but please feel free to comment or suggest others.
1-simply drill and cut to the next size up (3/8-18npt) drain plug (currently at 1/4-18 npt)
2-use the thread repair compound in the picture (prior use-good stuff)
3-drill & press some sort of bung so I can stick with the same size plug
4-shut up & let the machine shop address it no questions asked
I am leaning towards 1 or 4 or a combination there of... What do you all think?

It's going in for a hot tank treatment today. Definitely needs cleaned out.
