In case you guys with the heater problems didn't know, they actually make thermostats with different temp settings, so the thermostat won't open until it's warmer. ( Instead of 185, it will open at 205 ), or something like that. Although going beyond that temp is dangerous, it will create more heat in your heater core lines.
I just did work on a Dodge Caravan that had a high temp thermostat in it, and the heat from those vents was ridiculously warm, almost burnt you when you touched the vents.
