Nice work but why did you decide to do it? Years ago it was fairly common; some people changed them back and forth seasonally but I thought it was a bad idea now with computerized engine management.
The reason it's problematic with electronic computer management is when the engine is warming up the computer senses the coolant temperature and adds fuel until it reaches operating temperature(sort of like a choke, except instead of limiting air, it adds fuel...same thing). Operating temperature is somewhere between 160-180 deg F for most vehicles. Running the 180 tstat USUALLY does not cause any issues. If you use one in very cold climates you'd probably be more prone to issues. And the issues would basically just be poorer mpg. It's a good mod, keeps the engine cooler (lasts longer and provides a small increase in power).
