I once read an engine rebuilding book. The author of the book
specifically warned that the engine needs to be operating in a
proper temperature to keep at minimum cylinder wear. It is also
the reason the engine needs to be brought up to the operating
temperature as fast as possible. The author gave an example that
the very first cylinder right behind the cooling fan behind the
radiator always suffer more wear than all other cylinders. It
is the cylinder that is always cooler than other cylinders.

I believe the proper operating temperature for the engine is
as Scott said 190 degree F.
