Absolutely correct!
Top ring installs inner bevel up.
Second ring installs notch down (to scrape oil from cylinder wall when moving down).
Oil ring spring (the wave shaped piece) installs with ends facing down.

Don't forget to set the 1st and 2nd compression ring end gaps! Or ask your shop to it for you.

Gapless rings... they might work but I didn't feel like experimenting this time.

Good thing I've not started building anything yet.

Never even heard of gapless rings before. Why are they good....or not?

Taking a closer look at this, Mait, it would appear that the rings are , indeed, conventional.

The top ring is the "torsional" type and installs with the inner bevel UP.

The second ring is the "napier" type and installs with the "notch" DOWN.

Does that sound correct? I'm sure I'd have discovered it eventually but it's nice to have it straight in my head now.
