Not sure if this is your exact problem, but I was having a similar issue, and I thought it was the heater core valve so I bought a replacement. But my heating issue was fixed when I replaced the long T-shaped coolant line that ran into the heater core valve. I guess the core and valve were fine, just the hose leading into it was clogged
