flow wont be restricted and it will flow too fast through the radiator.... it will not be able to dissipate heat quick enough and will eventually over heat.
it will take longer to get warm because there will be flow as soon as you start it and it will stay in cold start phase longer (low ECT temps) and will use more gas....a lot more

I replaced my stat yesterday and thought about going colder but I decided to stay with my 195 sense my truck barely hits the "n" mark I don't think I want it to run much colder

I answered that question already....
if you could read the fuel map you'd see where the Optimum temp range is
The Fuel map looks like an X for the most part where the Cold start Multiplier weens out and then the normal mapping then back into a Fuel % add for the hotter the temp of the engine....
every location is different according to air density and altitude....as far as what the engine will like temp wise.
the hotter you run an engine the greater the spread of the heat cycle which means the more the metals grow and shrink eventually leading to cracking........ Mopars have always been the worst for heads cracking between the valves from the spark plug hole.

Probably not a bad idea to run the old 4.9 a little cooler then, if the higher heat cycle helps to crack the head. I've had copper seal in mine for three years for just that problem!

You are also talking about a newer OBDII system with more advanced fuel handling. Older fuel Map systems use a set grid or table as DrB said. Newer systems can be nearly infinitely adjusted.
