I like running lower temps simply because it helps with longevity of the motor.
Race engines do like to run hotter, but many times thats a materials issue. The comp cams spring that many lsx guys run are significantly stiffer than stock. The result is that they can become brittle when cool. As a data point my car runs 205-210 on the track and oil temps get ~255-270.
As far as the car running rich when cool, I don't really see that as an issue since most modern cars have charge air temperature as one of the variables they monitor.

Do you run a MAF tune or Speed Density? I was considering switching over to Speed Density. . .
