I suspect that if you are reasonably religious about keeping fresh oil in the engine and keeping the coolant topped up, etc. that 20 or 30 degrees of water temperature isn't going to keep the valves that much cooler. Also, putting a cooler thermostat in the engine will usually reduce the mileage a little (something about thermal efficiency, I believe). I used to run a 165 degree thermostat in my Triumph GT6 during hot weather (Kansas City summers can be warm) to keep it from overheating in traffic, and change to a 180 or 190 when cold weather came around, but this was just to keep it running a little smoother.
