A puzzle, finishing someone else's rebuild

All--

I bought a old A4 build-in-process from a guy that ended up going diesel. So it basically came as a partially assembled short block and a bin of parts. Basically, I got an A4-in-box and now trying to figure out what been done and what needs redoing.

As a bit of foreshadowing, the bores were not cross-hone, the numbered pistons are all in the right holes, but the arrows are all pointing towards the flywheel. (sigh) And half of numbers on the connecting rod/caps are on the side with the cam.

The block has been stripped of paint, but water jacket cover looked like it had never been removed... and that was true. I broke 4 of the bolts removing the cover and it was full of scale.

So I just pulled the piston/rod assemblies and found a bit of good news. The crank was ground and rod bearings are new. Also, the piston rings are new as well.

Since I don't have any docs on the what he bought and some of the assembly has been incorrect, how do I determine if the rings are installed correctly?
