Engine coolant routing.

[barkster1971]

I've put in an 80 degree thermostat. However the pipe from the top of the head to the radiator gets hot. Surely that would be a better place for a thermostat?
On a redblock you have the thermostat at the top which prevents coolant going to the radiator until warmed up.
On the D24 it is immediately going through the rad and the fan is spinning. Surely this isn't great as I want the car to warm up fast as possible?
I am going to put in an electric fan anyway but the thermostat only opens once the cooled coolant passes through the rad and along the long pipe back to the block.
i am going to put a better oil cooler in to. Could the pipes be then joined to allow coolant from the back of the head to circulate better?
What are peoples thoughts?
