opening up the heater valve by running the heat full blast may get uncomfortable, but I've found this method works very well since it allows the head to have more than one open passage to circulate coolant in. It needs a high RPM like a couple of miles down the freeway to do this and yes, a Stant thermostat is what I would use too. Makse sure you have no leaks, turn on the heat when you leave the driveway and keep it on full and go. I've never had a problem burping this way!
