Proper Thermosts temp for 318

I lived in New York 99% of my life. So cold I understand.
I used to run 180* thermostats. Heat was fine.
Switched to a 195, heat works even better.

A hotter engine doesn’t perform better, but in a daily driver where your not overly concerned with performance but more so with defrosting your windshield and being warm inside the car when it’s cold outside, I certainly suggest a 180* at a minimum and liked the 195* better.
