I'd say one of your problems is trying to use locking pliers.
I would heat it up and use an extractor if the bolts aren't already too messed up.
If you have headers on it, the bolts shouldn't be too bad. Someone already had the fun of getting the factory studs and bolts out.

the extracter doesnt work because the bit is to big to get inbetween the bolt head the tubes,
i know this would be total half a**, but the header leaks because of a crack in the gasket, except for the three bolts that are stuck ive put all new bolts in...
if i wee to tighten all the new ones and run a bead of jb weld do you think theres a chance thatll work???

It will still leak. The pressure coming out will blow that jb weld right out of the way.

did you try it with the engine hot?
did you try tightening them a little after the PB blaster?
Use a small cutting wheel and grind the head fo the bolt off.
OH, and EVERY time I do mine, I use anti-seize. Same with waterpump/ thermostat/ timing chain, etc.

still having the problem, tried it hot/cold, with extractors from sears, with a blow torch, with something called freeze brake...
guess just chisel em off, any advise...
this is the only engine problem ive had so far, but i cant tune the truck right with the lack of back pressure it back fires...

chisel em off then, pull the remaining studs and replace the bolts

as steve said before, grind whats left off or chisel em off, yank the header off so you actually have room to work, then carefully with a torch slowly heat around each bolt then while its hot give it a shot of pb blaster, the heat actually sucks the blaster into the threads then grab a good vise grips and just start slowly turning each one, itll let go eventually, you may have to repeat this several times before they let go but it beats drilling. this has worked very well for me with busted off manifold bolts. but first you need room. and dont heat it till its red! just get it hot.
