Ed...
I will agree with you that the lower thermostat will reach full coolant flow sooner, but both will reach full flow. I have seen demonstration in cooling system seminars where temp readings were taken on the sides of the engine block. The higher temp thermostats actually yeilded lower readings on the block. Same vehicle, same day, the only difference was we changed thermostats. Why?
As for the intake manifold, without the coolant bypass tube I doubt it would be cooler if the block is hotter.
