Definitely use heat. Those bolts have been through so many heat/cool
cycles that they are pretty much tightly sealed with that holes. If you
don't use heat, you will almost certainly snap the heads off. Anyway, if
your lucky enough to have bolts and not weld studs, I'm happy for you. If
they snap at least you can get them extracted...
