Dave, I appreciate your recommendations.  I've tried to test the gauge
before without removing it from the dash, and I got misleading results that
delayed my determination that the gauge was inaccurate for a couple years.
At that time, I had had the gauge professionally rebuilt and assumed that it
would have been properly calibrated, but it wasn't.  I won't be satisfied
with the condition of the gauge until I test the sensor directly in boiling
water and it puts the needle on 212 and no higher.  The only calibration
points on the gauge as I see it are at 212 and 132 - 141 (?).  The first is
easy to achieve precisely, but the second not so easy.
I've pulled and installed my radiator so many times I can do it in about 15
minutes.  Last time I had it out, I blew out the fins with a compressor.
Not much came out but miscellaneous bugs.  The fins are fine.  The interior
may be plugged, but it looks O.K. as far as I can see through the filler
neck, and the coolant is never discolored or has any particles in it when I
drain it.
It's a long-running problem only when I'm down south.  When I take the car
north, I have no problems with "overheating".  It runs at 190 all day on the
road.

Steve no need to remove the gauge. Just stick a thermometer in the radiator
before it gets that hot or leave the cap off as it warms... the blanking
sleeve and a "calibrated hole restrictor" in place of the thermostat should
give the best cooling results. 
 It sounds like this has been a long running problem. Put a bright light
behind the radiator and peer through from the front. Does the light coming
through seem correct or less than you would expect?
 Run a comb designed for radiators thorough the fins. Even small amounts
 of paint will cause constant overheating.

 Commercial hvac guys use a product called Nu-brite on condenser coils to
clean off grease and misc. foreign matter that is sucked into the coils. ~8
bucks at supply houses. Internet? Maybe..
