Ac heater control valve
If you don't care about OEM look, a photo of the water valve I put in my 1964 Valiant. I think it is OE for a recent Ford. I added a copper tube to route the other hose, to keep both off the valve cover. My slant-six has solid lifters, so removing the valve cover to adjust valves is a regular task. I have knee-knocker AC, so not essential to shut-off the heater core flow since in the different OEM climate box with own fan, but seemed wise while restoring. I had to tap into a wire inside the knee-knocker which is hot when AC on, which actuates the little vacuum switch beside the water valve. Same setup in my 1965 Dart and Newport. I retrofit my 1984 M-B 300D the same way since its electric "mono-valve" is erratic and expensive to repair, and later M-B used the same vacuum switch - valve setup. I used a different metal valve w/ gold chromate finish in 2 cars. Both type were ~$10 on ebay and both have a spring return, instead of the push-pull dual vacuum hoses I recall 1960's Mopar factory AC water-valves used. The vacuum switch shown is from a 1980's Dodge (have a box full). I used a smaller, cuter one for a Porsche on one car (cheap on ebay).
In case someone wonders, in the background on right is a GM coil to nearby 8-pin HEI module. On left is a 1970's Mopar Vreg. It seems smarter to mount that beside the alternator, instead of far away on the firewall as OE, to minimize wiring and make trouble-shooting simpler.
