You can't just pull the heads? That will give the party working on it a better chance, save you a towing bill, and honestly, it really isn't hard to do.

Re: Okay, keep your fingers crossed....
cheese;
which studs are broken, pipe to manifold or manifold to head?
if it's pipe to manifold try lots of heat, cherry red and visegrips on the remaining piece of stud,
if it's the manifold to head bolts, get out from under the hood, try working from inside the wheel wells, move,remove or cut the inner fender out of the way and make room to get straight on to the rusted,busted bolts, remove the manifold, soak the offending pieces with pb blasters and then try to back them out with a small center punch and hammer. the exhaust manifolds warp with heat and put enough side pressure on the bolts that they break when you try to turn them, once the manifold is out of the way and the side pressure is removed the reminants can usually be turned out. you should probably install new manifolds, hopefully with the new formula of cast iron.

You have to remember that I'm a Toyota guy at heart. They STILL use vacuum to control everything using pulse width modulated vacuum switching valves. Vacuum lines don't scare me.

Re: Okay, keep your fingers crossed....
ok cheese you need to put on yer big coveralls and: pull off the exhaust manifold.spray it down so you dont break the rest you have. once this is out of the way you will be able to see what you are dealing with.You gotta tow it anyways so rip it off.Chances are you wont be able to extract it with an extractor tool but if you have one,TRY IT.Then when that doesnt work,see if you have enough room to drill it with an angle drill,im guessing these are 3/8 studs.get the stud thats broke flat on the end and center punch it.Start with a small bit and work your way up to the tap drill.the angle drill being pried with a 2x4 against the inner fender helps big time.drill,tap,and get bussin the cheese!Hint; install studs instead of bolts on the ends for fitting!Post some pictures!good luck!Timbuk

Re: Okay, keep your fingers crossed....
To drill out studs: use left hand drill bits (sized to leave some stud wall and sized for the ez-out), drill all the way through the stud length, then do the ez-out.
I work on bigger machines--we use a magnetic drill press base--but the key is: left hand drill bits, all the way down through the stud.
