Default stripped cam sprocket bolt

I stripped the passenger exhaust cam sprocket bolt while trying to remove it.
so far i see a few options to remove it-

-vice grips
-tool for stripped bolts
-heat the bolt and hammer in a larger hex, wait until it cools and then try to pop it.
-weld a hex wrench in the stripped bolt

i tried the vice grips and they wouldn't hold the torque needed to pop the bolt.

would heating/welding on that bolt fuse it to the cam, thereby making a bad situation much worse?

I'd leave the heat out of it since you could hurt the cam seals. Welding is a good option but again it would heat the seal (not as much as a torch though)

This is a hex head bolt?

So you just killed the head of the bolt? If so get the Craftsman (or equiv) bolt extractors. They look somewhat like a normal socket, but have sharp grooves on the inside that grip the round head of the bolt. They work amazingly well.
