Run the engine with the fuel cap open. This sounds strangely like a non-vented cap problem.

You can use a piece of thin sheet metal to block off the exhaust crossmember -- one on each side.
Could be non-vented fuel cap...

Sorry for the lack of responses or updates.

It is boiling the carb at about 195 or so.

I have since blocked off the exhaust crossover and replaced the 3/8" phenolic spacer with a ¾" hard rubber spacer. I've also moved the radiator a little closer to the fan (now 1/2" between them) and relocated the trans cooler. I'm not sure how much difference the spacer has made, as I can now keep my hand on the intake. Carb stays reasonable, and not as hot as intake. Also, temps never reach 190° either. Seems to be resolved. I haven't had a chance to really test though. I just got it all back together today and need a thermostat gasket before driving.
