360 rings. gapless?

Gapless behave no different than std rings, you still set the gaps,

The top rings have no gaps,
2nd ring has gap
3rd ring oil

For the level you want, simple Speed Pro moly file-to-fit are fine.

Absoultely true. I want to be clear on that point like Moper said.

And what Duster Don said. Call KB. It can not hurt.
