I had an intake manifold stud break off recently and I'm in the process of removing the head in order to have a machine shop do the work of removing the broken piece. I tried removing the head by simply lifting it and failed to get anywhere. I can see where there is seapage of antifreeze between the block and head so I know it's loose, I just can't seem to lift it off the block. Any recommendations on how to do it, safely and easily?
