Should I put a 195 thermostat or 180 thermostat in my 2000 Ram 1500 with the 5.9l. It's got 202k miles. Any advantages with one over the other? I am pretty sure my thermostat gasket is leaking so I have to remove it anyway.

If you are experiencing any spark knock I personally use the 180° thermostat along with a little colder spark plug like the Autolite 3923Should I put a 195 thermostat or 180 thermostat in my 2000 Ram 1500 with the 5.9l.
