273 or 318 ?

While we're at this whole 273 vs 318 thing, anyone know what the compression height is on these eBay wonders?

I know the TRW variant of them numbered L2329F is 1.759, I'm guessing these would be the same.
NOTE: I messaged the seller and he measured them at 1.755. I'm contemplating a 360 crank ground down to fit in a 318 with a set of these on full float 273/318 rods right now. Not that it wouldn't be easier to just build a 360. But I've got most of the parts to make that happen more affordably than starting with the 360 I've got right now.
