OK, I figured out how to flush both heater cores. Neither was stopped up and even after the flush I'm not getting any heat, front or rear. I'm stumped. Any suggestions?

How did you flush the cores? Just because you got outflow doesn't mean that the cores aren't restricted. Are the hoses going into and out of the firewall hot? I'd start to think the warter pump isn't pushing as hard as it should.

The hoses have never gotten hot. That's why I figured one of the cores was blocked. To flush only the cores I clamped off the hoses that come to and from the manifold. The I cut one of the hoses going to the rear core and installed garden hose male to one side and a female to the other. Next I hooked up the water hose (using a backflow device) to one side and another hose to the other side and ran the end into a 5 gal. bucket. I turned on the hose and the water ran through the system pretty easily.
I was wondering if it might be the water pump. But wouldn't my engine run hot? If anything it runs pretty cold.

If your inbound hose to the core never gets hot, and your engine temp is good you must have a blockage before the cores or possibly the system is air bound. Why are you opposed to flushing the motor?

The heater core is no good and ur water pump is gone too.... no mater how many times u flush it, it won't work , i had my heater core done then my hoses weren't getting hot but i had hot heat and for 2min it goes cold, i found out it was my water pump .... so please don't keep wasting ur time flushing it. sorry

One could reason you got taken to the cleaners. Had the heater core done and still had no heat? Then the water pump? Nice that the shop you went to chose to go in order of most expensive first. If the poster doesn't have hot lines going into the core, then it isn't the core. Like I said, water pump or air bound.

I didn't get taking to the cleaners ,cause I didn't have heat until i did my heater core then once that was done i had heat but now I'm good... That why I said I was doing the same thing flush after flush and still no heat.... \\

If the core wasn't leaking, and it was flushed with no improvement, the first place I would have checked before ripping ther dash out would have been the water pump. Your mechanic went the $1500 route before the $300 route, but got you for $1800 in the end. It was probably the water pump all along. I'd say that's the cleaners.
