It's possible that in the winter I may want to swap back to a 195 depending on how well it defrosts the windows in winter; but for now I'm happy.
The question I have is this something that may allow me to advance my timing a degree of two since the head temps are now a bit lower and will this help prevent pre-ignition to any usable amount? I guess, from a programming stand point, is there a benefit to having changed this?

No, you may confuse the pcm and it may make the truck run richer. Thinking it is in a warm up mode all the time until it reaches the switch over to run temp.
