There's no reason the heat shouldn't work without the A/C. The defrost might not be as efficient, since it runs the compressor to remove moisture from the defroster air, but that's not a big deal. BTW, I have a '79 T/A with a 403 and A/C, too.

Agreed. The A/C system's job is to make a little radiator inside the blower box cold. If you don't hook it up, that little radiator doesn't get cold and you don't have cold/dry air. The heat will still work fine.

Just to clarify, the posts above are correct in that simply not hooking up the A/C compressor will not effect the heat. If you start ripping out all the vacuum lines, however, you may remove one that's needed to move the doors in the heater box from hot to cold or from heat to defrost. Get a factory service manual to figure out what stays and what goes.
