AM I ****ED? ehaust head bolts.....

Stud extractors work great if there's enough sticking out to get a good grip on. I've several that I use from time to time.

But on short, already damaged ones, they have the tendancy to chew away at what's left until you can't even get a pair of vicegrips on the remains. They're really designed to install/remove studs without boogering them up (or at least that's the theory). I'll go to the vicegrips right away while there's still as much meat as possible. Sure, the vicegrips will ruin the stud, but I'm replacing it anyway....

As Larry said, you should observe safety precautions with an open flame.

All good suggestions.
My .02 worth, spray it with pb blaster and let it sit for a little while, then use vise grips to turn it a little.

If it turns pretty freely(it probably will),then just unscrew it.

If it is hard to turn, turn it back the other way a little.
Then work it back and forth going a little further each cycle.Also, I would spray a little more pb blaster on it every few turns.

Ivan and Larry beat me to it.

That's the fella I was talking about.

Soak the studs with PB twice-mig weld a nut on the stud-heat from the weld will aid in the capillary action of the PB-after the studs semi-cool soak again with PB-when cool enough to touch try ever so slightly to tighten to crack the bond between the two dissimiliar metals-then try to loosen very carefully working back and forth-by all means practice patience and Good Luck!
