If it was me, I would flush the gapless and put a flat ring on top. I would also double check the oil rings. Make sure the rings are on the correct side of the spacer also.

I still think a dykes is good with a stick. Our old 327 275 ran 10.74 in E this year. They aren't toobad and we never have issues with oil. You can turn the shortblockby grabbing the end of the crank snout too.
I don't doubt you Jim, and others say the same - yet just as many say they love the gapless top. Also, I don't see how the top ring could affect the oil control to this extent.
I agree that the bores don't look too hot. This wasn't a fresh bore, just a hone job, but the guy that honed it builds quite a few gapless engines so I figure he knows what he's doing.
So it appears that the consensus here is rings? No other things to look for?
