I'm thinking I should maybe put in a different thermostat valve to get the temp up into the 200s.

That sounds like the best way to accomplish your goal. I may be way off here, but when researching the crap out of efans I though I read that the stock thermostat (on the 5.4L Tritons) is at like 190 degrees. If that is the case I would think that Ford found this to be the best operating temperature for our 5.4's and is probably best left that way. Is it benefical and/or safe to try and increase the operating temps of our trucks?? Again, I may be totally wrong here so please don't shoot me!!!!
