How about a block in the heater core, or one of the lines running to it?
A chunk of rust or other debris could have come loose inside the
radiator and made its way to the core.

Try disconnecting the two heater lines *from the block*, force water
into one of them (making sure the heat control is set to full hot), and
see if it comes out the other. Then force water into the other hose as
well, so if something is clogging it, it may be forced out.
