Yep, trying to rush through too much on that day.
I think I may have posted that the rings were on the pistons ready to install before it was decided to give them more gap.
I was busy cutting and re-welding the 1/2" oil pickup tube that was too long for the oil pan, and my friend and his 11-year old were working on the pistons, but I think I screwed up telling them the rings go with the bevel to the top.
Not sure how #3 got installed without compression rings. Anyhow, I'll have to pull them all out and get it corrected. Will see how good the Cometic head gaskets re-seal (with some copper coat), and the Jegs windage tray/oil pan gasket.
