Remember, you are human. You are a victim of humidity/ temp and time. your engine is only a victim of temperature vs time.
If it's 84 degrees, that's nothing.
try being here when it''s 115 outside and you have that hill to climb.
You may have an airflow problem, water restriction, radiator condition, engine RPM not being in the power band when climbing that hill.
hook up a tach, and make a mental note of where the temp is on an 84 degree day at certain RPM's.
Also, you may need to install an oil cooler to cool the engine further.
Try installing a separate trans cooler so the trans fluid going to the radiator does not help heat up the water.
There's a few things that can be done to help cool.
Where is your timing? try retarding the timing 2 degrees.
Synthetic oil or synthetic blend drops temp about 15 degrees.
How many fan blades?
clutch fan or direct drive?
where is the shroud placed in regards to the fan tips?
Do u have a coolant recovery tank? If not, you may have a big air bubble in your radiator tank instead of filling it full of coolant
If direcct drive, is there a fan spacer?
brass/ copper radiator or aluminum?
do u have a bug screen for your radiator? (catches small seeds and tiny bugs)
What kind of pan do u have? is it steel or aluminum? How many quarts?
How close is your exhaust to either the pan or the oil filter?
What oil filter are you running? the tall oil filter holds another half quart of oil
Have yhou checked your fuel filter lately? a restricted filter leans out the engine and makes it hot

It all comes back to details. The more details you address, the less trouble you have.
