The only way to do worse on the highway is a cooling system restriction somewhere like poor airflow, clogged rad, etc. Are you sure your lower rad hose isn't being sucked shut when at higher rpm? You're supposed to have a spring in there to prevent that.
If the spring is in the lower hose, then it's lean. That's why it get's hot under power. Lean and timing is why most guys have temp troubles.
And leave the fan on it, it's not blocking air flow. What's he supposed to do when he slows down without a fan?

As said check actual temp. Boiling out is not terribly effective in alot of cases. I say need to swap radiators. Can toss the stat for a 1 hour test as it may not b opening all the way which causes a restriction "at speed" but OK around town & it's easy to test but way less likely that it is a stat prob. If the sender in the wp housing is bad it'll give erratic/inconsistent readings but you said it's consistant but just showing too high on the gauge right?

I have a 440 that had the same problems. Wound up being the timing. When I switched to a Mallorey unit that adjusted it made all the difference..My dummy gauge on the dash reads the same as yours and I also have a mooneyes temp gauge that reads around 185...not a problem..

WORSE on the hwy ? ..take the fan off ...and try it. It could be blocking air-flow at speed.
Ummmm... That's like drilling a hole in the boat to let the water out...
OBVIOUSLY our good-buddy Goin'Commando has limited Xperience with boats ...
IF the boat is moving .... and you pull the plug out of the rear of the boat .. any water in the boat will flow-OUT very nicely.
And the same basic premise applies to a cooling system on a car. Past 12-15 mph(or so) .. the forward movement of the vehicle is enuff air-flow to cool the rad. I know a guy who ran a 4 banger Omni for years with a uNfunctional electric fan(due to some electrical issue he could never seem to track-down).
He wound-up putting the fan on a manual switch IF he ever got catch in bumper-to-bumper traffic.

You are assuming he has an electric puller fan on his stock set-up? Not sure he mentions that in his post. Unless you suggesting he remove his stock mechanical fan? That is not going resolve any issues.
I will agree with other posts and say you are either lean or you could use some more timing.

NO I am not at all. I am assuming he has a stock mech fan on this ..of some sort. And to remove this fan(a EZ task in most cases) to do a quick test ... to see if this is the issue...?? ... and are you suggesting that a mech fan that is spinning around .. that is close to the rad ...CAN NOT block the flow of air through the rad ?
And if there is a LEAN ISSUE that is causing this ... it would have a major lean-surge during this over-heating.

wrong, it can be lean and not surge.

I am not even really sure how to respond to those questions. Obviously I am not on the same wavelength with you. I guess he should remove his fan all together? Then what is the solution?
BTW, you can be lean and not surge......too much timing is usually what will cause the surge.

I am saying that he should try removing the fan .... on and for a temporary test only.
And YES it can be lean and not surge ... but if it is LEAN ENOUGH to cause a overheating issue ....it will in most cases be surging also.

Fun read. No/little info from OP results in outstanding reading-fun.
For all the overheating topics we have had in the past.......removing the stock fan is definetly one of the more well thought one's I have seen in a while.
Seriously though, there are a lot of past posts on overheating with some great information. Start with the simple things, like hoses, and T-stat, then start into the tune and the timing.
