Ok. Well 110 is certainly too high.

with the infrared temp gun, i know that my 80c thermostat is opening around 85, as measured on the thermo body, so 90 operating temp on the gauge probably is normal for this thermostat

Well if the T stat is working as intended maybe some kind of blockage or maybe not enough water flowing thru the system. Maybe the water pump?

my attitude now is i can live with it, but i'm going to take a shot at lowering the temp, with a citric acid flush -- i know that when i replaced the radiator in my old 6.2 diesel van, there was a dramatic drop in temp

I will be doing that as well when I replace my T-Stat and heater valve on the firewall. Mine is leaking when I use the heat - on the one or two days every few years around Jan 01st when there is a point to using it in Phoenix.
One thing I will do, and you might consider this yourself is to disconnect the heater and flush it seprately from the engine flush. Might be gunk in the heater core that you may be able to get rid of more effectively doing it seperately than just doing a straight engine flush.
