Well, I should probably clarify just a little on removing an epoxy cemented head; you can remove it with heat but you need to use some extra caution because it takes a little more heat then it does with the hot melt glue. If you're not careful you can overheat the ferrule of your BH. So to be safe, if you think you're going to be changing the heads on your shaft with frequency then you'd be better served with hot melt glue.
