Guys,
I just got my a/c working, but I'm noticing that even while the dash vents are blowing cold air, the defrost vents are trickling out hot air. Slightly counterproductive. Has anyone else dealt with this? I suspect that this either a vacuum issue or perhaps some foam seals in the dash have rotted out, but I'm not sure.

Your heater valve is not shutting off.
The core is staying hot and the def vents are just where it happens to be comming from with the floor ducts closed.

How is the heater valve actuated, and where is it located?

I ended up blocking the flow of coolant to the heater core by clamping a piece of a bolt into the line. Eventually I'll replace that with an inline shut off valve.
