Well you can either buy a whole new head or there is something else you can do to it I can't really think of it off the top of my head though. There is another thread about this on here somewhere about the other thing you can do. Just keep looking.

Get a helicoil. You take the head off, drill and tap a bigger hole where the old one was, and put it in. Its just a threaded insert that you'll put back inplace.
