Cars running too cool?

My car typically runs 160* to 180* as I sit in traffic and while driving down the road . . . is that bad?

I would want a car to run at least 180 with iron heads, and 190 with alum heads!
will get a more efficient burn.

And I do have aluminum heads . . . so why?  I typically thought the cooler the better?

160-180 normally makes the most power on the dyno

Fuel atomizes the best normally with a 180 degree thermostat which will put you around 190-210 degrees. I doubt you are losing a ton by running cool and I would bet most folks would be envious of your cool running motor. Of course this can vary by motor.

Fighting the other problem is always a huge pain.
