Make sure the valve is opening and closing on your firewall. If everything is working properly I would take the heater core hoses off and blow out your heater core and flush it out.

does it get hotter as you drive and cool down when you come to a stop? if so maybe it has an air pocket

1. Check valve by the firewall, make sure it's open
2. Did you bleed the coolant properly?
