My #1 suggestion, especially when dealing with an iron block and aluminum head
is: change the head gasket. Combustion gases leaking from the chamber INTO the
coolant will send the temperature through the roof and you won't be leaking
except for what's turning to steam and escaping.

  Have you checked compression? Usually when an engine overheats it is from
the before mentioned problems. SO, if the water pump is pumping and the
problem continuses after the thermostat is changed and you say the radiator is
flowing(has it ever been rodded out?)- the heat has to be coming from the
engine- usually a blown head gasket. When a head gasket blows one or two
things happen. ONE- water gets into the oil or two- compression gets into the
water. Since you arent losing water (antifreeze mixture) and if the gasket is
blown then compression would have to be heating up the water. When you shut
the engine off- Do you hear a gurgurling sound? Like the water is boiling
inside the engine- does so until the temp drops down?? If not and a
compression test shows the same pressure on all cylinders, I would start
thibking about finding another gauge oand or sending unit. Have you used a
heat gun( that measures temps) on the outside of the engine to know what
   the engine temp is ambient wise?
  Im getting at if you have no other signs of a problem besides the gauge you
need to prove to yourself the engine is hot. Does it boil over or bypass the
radiator cap? Does the engine ping from it getting to hot to drive? IF NO to
all questions- go make sure it is really hot and not just the gauge or sending
unit showing hot. Good luck.
