Man, that sucks big time. The block is the one big chunk that you can't fix by just bolting on a simple replacement part. That hole is big enough that it will be a pain to find a thread tap, and pretty unlikely that a thread repair kit is available.
If you're willing to give up on the block heater, I would try calling a local welding outfit and see if they'll do aluminum - Just have them weld a thick plate over the hole. It would probably be cheaper than a replacement engine, but unless they do house calls, you would either have to pull the block out or tow the car to their shop.
Failing that, drill the threads down smooth and find an appropriately sized expanding rubber stopper to fill the hole.
