RE: [DML] Exhaust stud removal

More heat and more liquid wrench. If you still have threads
left, you should use 2 nuts to get the studs out. Put one nut on
in a position where you can get an open end wrench on it, then 
snug the second nut (called a stop nut) on and tighten it against the
first nut. Then heat the area around the stud with a torch for at least
20 seconds, moving the flame around the stud. Don't heat the stud.
Steel expands faster than aluminum, so heating the stud makes the 
problem worse. After the 20 seconds, spray the stud with a blast of
WD-40 or liquid wrench and start turning the first nut immediately.

If your threads are mangled, there are stud extraction tools available
at any parts counter. Use the same procedure using the stud extractor
instead of the two nuts.

I need some advise. I'm replacing the exhaust mainifold gaskets 
and everything was going okay, until it came time to remove the 
studs.
