My 70 Cougar came with a/c but it has been non-operational for some time. it is my understanding that the water valve only receives vacuum and closes when a/c cool is selected, either max or fresh. if you are not running the a/c, is there any reason to keep this valve in the system? it's just a lot easier to route the heater hose out of the way without this valve in line.

are most of you running the heater hoses back to the firewall along the intake manifold by the valve cover, or somewhere else? thanks-

No reason to keep the valve in the line, but make sure you plug the vacuum line. If the valve is in decent shape keep it in case you change your mind about a/c. If you are not planning to change the hoses, I would leave it alone.
