Or burn them out. If the stud is over the water jacket, first drill a 1/4-5/16" hole all the way through into the water jacket. Then with a cutting torch get the stud good and red before hitting the oxygen lever. Stay on the lever until you have burned out the entire stud. The rust around the threads acts as an insulator keeping the block threads from glowing red and also burning. If metal is not red hot, the extra oxygen from the cutting lever actually cools off what you're trying to cut. The hole you drilled lets the slag blow away instead of back at you. With a little practice all you need to do is chase a few crumbs.
