So today i went to change the plugs and maybe give the old ST some more life and i found a terrible surprise. A previous owner welded the plug in place, i would say the bead is about 3/8" long. I guess they stripped the threads and were too lazy to put in a Heli-Coil. i tried to take a picture, but the flash didnt go in the deep hole. I cant change the plug obviously, i guess wait for the plug to go bad and then worry about it. So is the head salvageable or would i need a new one after the plug goes?

2nd. You can, but it's really hard and it's extremely hard to make it hold well at all. Tapping it and putting in a oversized ring around the spark plug (heli-coil) would be so much easier. I would hate to try to weld down in a hole like that. If someone actually did that, I would be more impressed than anything. It's salvagable too. I can't see how you couldn't get it out of there. Worst cause senario you pull the head off and go at it from the inside, drilling it out.
