2000 jeep grand cherokee laredo wanting to overheat

Wants to overheat and go into the "red zone" but as long as I keep the heater on high/defrost and go above 35 mph, it seems to stay just past the line before the red zone. If I'm going slow then it creeps towards the red-zone but as soon as I'm going fast again it seems to cool off.
I've had the transmission flushed, the radiator flushed, put in new thermostat & gasket, new water pump, upper & lower radiator hoses, temperature sensor gauge and fan clutch.
No water in the oil or smoke out of tailpipe. Could it be a cracked head or ...?
