It it's less than 50 outside, you could always wrap some aluminum foil around the engine head. That's how I broke in both my new motors. I was getting readings around 230ish when breaking in my 2.5r with the foil on it. After breaking it it, I took the foil off and the temps dropped dramatically really fast. Settled around 170 or so.
The key to breaking in a motor is making sure the temps never go below 200*.
