I'd warm up the engine, turn it off, and spray the bolts with liquid wrench..
Wait a while, give them another good shot of liquid wrench, and maybe let it set for a few hours.
Usually after a couple of applications the bolts will 'break free' without twisting off....
We've broken off a few exhaust manifold bolts, and it's a PITA drilling them out, especially if you are running aluminum heads. :nonono:"Ad eundum quo nemo ante iit" -
Damn you guys must have bad luck, On both my cars the manifolds come out real easy. I just need to get my cheater bar out to make it easier.

Yeah I've not really had issues getting SBF manifold/header bolts out even after being really old. None of them needed a big cheaer bar or really a whole lot of effort to break loose. They're an exception though.86 Lincoln Town Car (Galactica).

I spreyed it with pb blaster the night before I did the exahust. Spreyed it a few times. Drove around. Next morning went to do the exahust, spreyed some more on it. They came off like butter.Originally posted by Grand_Marquis_GT1989 LTD Crown Victoria LX.
