Newer engines are built with close tolerances and the engine control modules are temperature sensitive. i would put in the proper thermostats. The older engines without ECM can survive without tstat but engine wear will increase. Tstat are cheap but good investments.

If you drain the block for winterizing, you may want to drill a 1/4 or 3/8 inch hole on the flat plate that holds the spring mechanism. That will allow the water to drain.
