Don't you have over 500HP? If so, it's going to run hotter than most others running at 325 HP. If you stay at 210-215 it's not a problem. It's when you climb to above 240 when you start to have issues.
Today's engines are tested with various methods similar to those back in the 60's. One being a thermal shock test running WOT 10 minutes at 240 deg, and shocked to 60 degrees in about 2 minutes or less, then 10 more minutes at idle 60 degrees, then WOT (peak HP or peak Torque)at 240 again. That's a standard test which is no worse than any road conditions unless you overheat (240 and up).
Make sure you have a 50/50 mix of coolant/water, more coolant will make things worse not better. Timing will also affect your temps .
