I have seen the heater return line (on the LH side of the engine) get
blocked with sediment or even kink/collapse.  Might be worth checking.

If you still can't find the problem, a fairly extreme test would be to
disconnect the return line from the water pump, put a plug in the hole, and
briefly start the engine.  You should get a solid gush of coolant out of the
tube.
