I thought the temp valve was to turn the EGR off until the engine warmed up, but now I see in that diagram/remember that there are two. I don't care one bit about being stock or the EGR, but that sounds like a worth while feature to have.
You have any idea what temp the valve trips and how I can tell which is what, IIRC they are colored different?
EDIT...
Wait, now I'm confused, I'd never set it up like stock, but I could see using that valve to perform that function. However I'm confused about how it's set up stock. What does it have to do with vacuum advance?

Ford engineer "Let's detune this engine through a complicated mess of superfluous vacuum lines, fittings and valves. That way it will be more likely to fail, get worse mileage, have less power, and overheat. That is until it actually overheats, then we'll give it proper timing, can't be replacing whole engines on warranty."

I checked this gray 2 port switch in my t-stat housing for the EGR, it is closed cold and opens to let vacuum through at 150 degrees , that works I guess.
Thermostat stuck while testing so I changed it again and used a Fel-Pro black and orange gasket #35041T cause I used the funky paper gasket when I changed the Tstat last week and it weeped a little, well the fel pro gasket leaked as soon as I started it. I've had enough for today I'm beat. Tomorrow I'll deal with my water leak and try moving the vacuum advance hose to the middle port.
Thanks for all your help guys , Gene

Sometimes the thermostat housing has been overtightened and the ears become warped.
If you have a piece of wetordry sandpaper you can try lapping it flat using water to suction the paper to something flat like a counter top or plate glass.
Always work it in a figure eight motion.
This might solve your coolant leak.
