Since the radiator level is correct, I don't believe it is air that is causing the noise. It could be coolant gushing through causing the noise and you can try back flushing to see if heater core is clogged.

Im gonna try back flushing the heater core. If that doesnt help, it is always hot here so I really don't need my heater, is it a good idea to just bypass the heater core by plugging the flow line into the return line of the heater core and eliminate it?

If the heater is not required, that would be the best go about.
Over here we do that all the time but for some vehicles, of which yours is not included, bypassing the heater can result in excessively cold A/C temperature setting which cannot be controlled. This applies to vehicles with climate controls.
