top of ring is where the gap is to fit around the locating pins in the ring land normally
I would look closely tho as some sellers buy parts from wherever they're cheap, so there may be pistons with pins other way around.
honing may or may not be possible on these - years ago, I would hone carefully to just break the glaze the tiniest bit, but on some more modern cylinders I think the chrome may be thicker, so I'm trying to get a bit more definition in the crosshatch - this could be an unneeded risk tho
