Are they? I thought it would be cool to run a 486DX2-66 at 1x and 66mhz fsb. 🤣

If you can can get your hands on the 0.8 micron 486DX-50, you can probably get away with 66MHz. It's the same process the DX2-66 uses. I tried it once and it seemed to work okay with a heat sink. Not very practical since 486 motherboards aren't entirely stable at that speed though.
3.3V DX2s can usually have their multipliers set to either 2 or 3 (but not 1)

How would you tell if it was 0.8 micron?

You can examine the die casing. Should be smaller like a DX2-66, not like a DX-33. Looking up Sspecs might help too.
My understanding is that the majority of DX-50s should be .8 micron. I believe intially intel tried to manufacture the chip at 1 micron, but there were cooling issues. So there was a recall.
