Exhaust studs with headers?

Well, ****! I tried 3 times to weld a nut to the broken stud. It breaks off every time I try to turn it with a wrench. Hopefully I can get a drill and tap in there so I don't have to pull the head. Why does this crap always seem to happen to me? Haha...

My #7 stud snapped off and I tried all the tricks, working my way down to the drill and easy out. (the easy out snapped off in the hole about 1/4 inch in)

Since I am using Remflex gaskets and I plan on swapping heads later I just put it all together and got no leaks at all over a year now.
Those Remflex gaskets are everything they say they are, and you don't have to re-torque them later either.
Worth every penny.
