Re: BOLT head in the Bilge...
If you can manage to get a scissors jack under the engine, you can fit it up to support it when you remove the bracket. If your luck holds, there might be a bit of the bolt still sticking out of the block -- hopefully enough that you can gain a purchase on it with a pair of vise grips or a small pipe wrench. If not, then you'll need to try an easy-out.
Like mentioned before, pretreating with a good penetrating oil should be your first through third steps (apply, tap lightly and wait; repeat; repeat).
