Good to hear of your experience with rebuilding the heater valve. That's on my to-do list eventually. I think you can pressure test it by dialing down the output on a compressor and putting some air in there while "sealing" the tubes with rags or something. I'm not sure on a '56, but on '54 the choices were either 7lbs or 13lbs caps for the cooling system. So I would guess if you put 13lbs of air pressure in there and didn't hear any leaks (or put it in water for visual) then you'll likely be fine.
