Wont looping it just rotate hot water around the motor (shortest path) reducing flow to the radiator as well as heating the front of the head up?

Thats why I asked, most people loop, but with the 1200 having a coolant shut off valve (no coolant flow unless heater is used, and when heater is used it acts as a small radiator removing heat out of the coolant)

I see looping it adding a lot of temp into the motor? maybe im not seeing somthing?
