Judging by what I see...
You needed to also have a ridger reamer becuase the tops of the bores cocked the stones. This ridge has a very good chance of breaking either the rings or ring lands if new rings are used.
It looks WAY too rough. Did you use any lubricant on it? What are the grit of the stones?
The way the stones did not contact at the bottom of the bores tells me the bores had a ton of taper and it really should have been bored and new pistons installed.
