Ed,
I think Ken is right about the combustion gasses leaking into the
cooling.  That is what mine was doing.  How does the list feel about
retorqing the heads if the outer coolant seal is not leaking?  I know
there is a chance of displacing the sealant under the head fasteners,
but it would be easier than pulling the heads all the way off to replace
the copper ring.

Ed,
The internal head gasket may be leaking combustion gasses into the
cooling
system. Do you notice a steady stream of bubbles into the reservoir(the
tank
with the blue pressure cap)? The water pump could be shot. The
thermostat
stuck, radiator clogged(does it get hot?). Does the radiator fan work on
all
speeds?
