Ok, is the coolant level ok though? Might have dropped a little since repair if there was air in the system.

That gray hose will only keep the vents from switching properly. It shouldn't affect the heat itself.

What about the vacuum line that goes to the shut off valve on the heater hose? On top of the passenger side valve cover.

I had the same problem after deleting my EGR and coolers. Turns out I had a MEAN air bubble in the lines. I got it up to full operating temp, turned the heater on full blast and went under the hood and pinched and shook the crap out of the radiator hose next to the driver side battery. I could watch it burp the bubbles into the reservoir.
