Do you have a mechanical or electric fan?

Hot at idle or at highway speeds?

You indicate the electric fan and the motor fan are working. The motor fan may appear to be working but not engaging (locking) when the temperatures reach a preset temperature. You should hear the engine start to roar when the fan locks in at a higher temperature. If you don't hear this roar (like downshifting a gear or two) then the fan clutch is faulty. Not an uncommon problem.
If you do hear the roar then I'd suggest a good internal/external cleaning of the radiator.

Make sure the engine base timing is set correctly and that the timing advance in the distributor is working correctly.

Since you have an infra red thermometer, you should be able to aim it at different parts to see what is hot. Make sure the radiator, air conditioning condenser, and oil cooler are all free of bugs and debris so that air will easily pass through.

When does it overheat? Highway driving? slow speed? pulling hills?

Its electric and clutch fan
Its hot at idle and highway

It does roar when you leave a stoplight for maybe
two minutes not long enough for temperature to come down

Thank

I would do a flush and fill. I have seen a water pump where most of the blades were eaten away from corosion due to lack of maintaining anti freeze.
