Mine was an 180f, with a hole for an air bleed. I found thermostats open at there rating but dont fully close for 10 degrees below. I guess the spf cooling system is so good / large I had ample cooling with a tiny hole in the 180F. I tried numerous 180f thermostats and all the same result very slow warm up and never above 165F except summer. Now with the 195F I warm up and 95% of the time in summer I am still only at 180F!!!! yes I checked the accuracy of my temp guage and it was dead on!

In speaking with Roush the other day, I asked them about using a 180 degree thermostat. They said to use a 160 degree standard flow thermostat and drill a 3/32" hole in the flange.
