Everyone read what ford4.9 wrote. He has a VERY good point: "if the hoses are reversed you'll hear a grugling sound as the coolant drops through the core. Since no coolant ever builds up in the core, you are not going to get any heat from it."
Stop and think about this for a second. Think of it as your old bathroom sink if it has an overflow hole somewhere in it. If water for some reason is reversed and goes through that overflow hole, it will go right into the sink and down the drain. If the "hoses" are correct the water will have to fill that sink until the water goes out the overflow. The core is not able to gather any of the heat from that water if its rapidly moving through it.
Reverse those hoses and I will lay money that you'll have heat. Complicated explination I just made I know, but just stop and think about it.

I can't picture how that would be the case as I looked at the core this weekend. I trust that it does make a difference based on everyone's experiences, but I still don't really understand why.

I have a heater core sitting in my driveway, so I know exactly what it looks like. It looks like there's nothing to determine a flow direction, because either port goes down one side of the core and back up the other. I just don't understand, though if people have had problems I believe that it must have to be hooked up a specific way; I just don't understand why.

Okay, Sorry about the delay. I finally got back in town and had the extra 2 seconds to look at the lines. Assume I understand the directions from quicklook2 the inboard fitting goes to the water pump outlet. this is the way it is hooked up.
So to answer the question on flip floping the hose it has not solved this problem the heating problem or the girgling.
My next direction will be to completely pull out the ducting and look for something hindering the doors and using my infared temp gun to find the blockage. does anyone have a systematic approach to doing this??
Thanks for the suggestions. Please keep them coming. It will be after Labor Day before I can dig into the ducting, so any additional quick checks are appreciated.
