Well the seller has basically told me to F-off and its not his fault since a shop removed the heads and they deny breaking a bolt off and as such won't do anything for me.
Thanks z2h8t for dicking me around on this and making me pay out of pocket for someone else's mistake. Should have just bought a new set at this point.

 

I could get that out in less than 10 min with just a small ***** punch. If you use a punch and tap it straight down a couple times (not hard, just a few taps) You will loosen the threads slightly. Then you could almost use super glue and something to back it out. There shouldnt be any force on it at all holding it so it shouldnt be tight.

Just be patient and work at it with a punch, a tiny one, slowly turning it out by taping it around. I get busted bolts out smaller than that all the time. If there is somthing on the threads (loctite) put a little heat on it.

 

I'd bet its cross threaded to begin with.

 

Been doing it for years to fix cross threaded spark plugs after a diy tried a tune up at home on a car with aluminum heads .
