Reply to "New motor, coolant temp creeps up between 195 & gets close to 230"

If thermostat did open, but not enough to block recirc, I would think the outlet to the tank and TO radiator would be as HOT.  

I don't have any experiance, but from a classroom heat transfer view, I would think the metal heads have to be hotter than the coolant
