My car has a gurgaling sound in the heater core when you increase the rpm and slow down. But when it is running at a idle it does not over heat, but when you drive it at high speeds on the highway it will over heat. I have done the LH head gasket and I have also done the heater core and back flushed the system, and it still over heats at high speeds on the highway. Thank you for your help

Feel your radiator from top to bottom, should be hot at the top and noticably cooler at the bottom, Also if you havent already replace the thermostat! Make sure system is full and there is no trapped air! Take the cap off and squeeze the upper hose.
