Besides I-94 and I-40 in national parks, which both have 75 mph speed limits. What is the highest speed limit on a two lane road in a park?

Presumably you would want the highest limit on a road maintained by the NPS. I know US 33 through Shenandoah NP retains its 55 mph limit (though hard to actually go that fast).
The answer might be Natchez Trace Pkwy with a speed limit of 50?
Spot checking roads in Death Valley NP showed 45 mph.

It doesn't have to be managed by the NPS, but that's a bonus. I found 65 mph in Death Valley on google street view.
Pretty sure it's 60 MPH on CA 190 in Death Valley National Park which I believe is the fastest two-lane.
US 191 dips into the northwestern corner of Yellowstone National Park, where its otherwise-65 mph speed limit drops to 55.
I-64 technically enters the New River Gorge National River, and the speed limit is 70 there (trucks 45), adding to the list of interstates.
KS 177 (Flint Hills National Scenic Byway) in the Tallgrass Prairie National Preserve is signed at 60 MPH.

National Preserves are not national parks.

It's still owned and managed by the National Park Service
Perhaps the Parks Highway (AK 3, secret I-A4) where it passes through a tiny corner of Denali National Park? I'll be darned if I can find a speed limit sign on Streetview.
SD 44 is 65 through Badlands NP. There are no signs within park boundaries, but it's posted 65 on either side.
CA 190 is posted 65 in the Panamint Valley portion of Death Valley NP: https://goo.gl/maps/ZgVU48aL89EbrYgHA

In my own defense I was going by memory on that one, there is indeed a 65 MPH zone in Panamint Valley. I think that I ever took a picture once of the sign.
The federal (NPS) part of the Baltimore-Washington Parkway (unsigned MD-295) between MD-450 (Bladensburg) and MD-175 (Odenton) is 55 MPH - that's more than 15 miles of four-lane divided parkway.
In Acadia nearby, part of ME 3 is 50 in the park and I don't think any other road in the park hits that, though I might be wrong.
I see in the 2021 Rand McNally that Indiana Dunes National Lakeshore has now been promoted to full National Park, so there is a section of US 12 to consider.

That's not that high.
I-40 crosses through Petrified Forest National Park. Its speed limit is 75.

I mentioned that, that's almost certainly the highest.
Guys...The Ohio Turnpike barrels right through Cuyahoga Valley National Park, with a speed limit of 70. But now that you mention I-40 through Petrified Forest NP, yeah, that's gotta be it.
What about I-90 through Badlands and I-94 through Theodore Roosevelt? I've been to both and I can't recall what the speed limit was on either.
US 6 has a section of 50mph near its end in Provincetown, MA. The last few miles of it are under NPS jurisdiction.

90 doesn't enter Badlands.
94 does enter Theodore Roosevelt, and has been mentioned in this thread multiple times. The limit is 75.

I-94 is actually in Theodore Roosevelt for several miles even has a dedicated vista exit:

For some reason I thought the northeast entrance tip of Badlands boundary followed SD 240 to I-90, it doesn't.

I-94 is the southern boundary of parts of Theodore Roosevelt NP, so it is not really "in" a National Park.

Yes, and even has a NPS Vista which is accessible directly from I-94. It very much clearly is aligned through the park. You actually travel over I-94 from Medora to get into the south annex. You could make that same semantic argument about I-40 in Petrified Forest.
I don't know how accurate OSM's boundaries are, but they show I-94 unambiguously entering the park boundaries between exits 25 and 27:

I posted the actual park map above somewhere. I-94 is decidedly in the park boundary and interacts with it far more than I've seen with other Interstates.

It's too bad that I-90 doesn't enter Badlands since it does appear to have a speed limit of 80 when passing by it!
How about Zion N.P. at I-15 exit 40? OpenStreetMap says the northbound exit ramps, but not the mainline, are in the park. Google Earth shows the park boundary in the median of I-15, so the northbound lanes would be inside the park.
A section of US 101 in Olympic NP is signed for 60 mph. WA 20 in North Cascades and WA 410 both have 55 mph sections in their respective parks.
