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