David,

I had a similar problem on our 87.   Finally solved by replacing the heater
core, which was clogged.   I didn't try power flushing it with cooling
system flushing/cleaning stuff first, (since the fan motor had started its
squeal of death and had to be replaced anyway) and you should probably try
checking the core before pulling the dash (real pain).   I think if you
used long hoses and a funnel, you could see if the core is clogged and then
try to treat it.   I don't have any experience with cooling system
flushers/cleaners, however.

If you haven't already, You should also check to be sure that the coolant
valve is opening all the way, and that the hoses aren't crimped somewhere.
