Good points, thanks! So took a complete piston into local machine shop. He confirmed the proper location, the dot is top ring, facing up. And the ring labelled "TOP" is 2nd ring with TOP up. So good news, I said I'm fine with buying a new set, but he said no need.
So I'll continue cleaning and check the lifters, all specs were good previous, so I'll plastigauge the 3 new bearings tomorrow.
Should I look at removing main caps for inspection? Everything was well lubed properly when installed, but finding what I did on 3 rod bearings has me wondering?
Thanks.
