1996 Ford F350 460/7.5 4x4. I have broken the spark plug off. All that remain in the head are the threads. I have lightly taped a screw extractor in and have broken a half inch socket trying to get it to budge. I have sprayed liquid wrench to let it set overnight. Is it OK to use heat or will that ruin the head.
have the same problem?
