Sealed Power chromemoly ring set
I can't find any information about this piston ring set. Summit:

Is that set OK for 350+hp daily driver?
Should block be prepared and honed like for plasma moly rings (finish with 400 stone)?
Or is this set junk and should I go with plasma moly ones?
How long will be break-in period with these cromemoly rings?
I don't wanna rebuild my engine in 2-3 years, so I need ring, taht are durable.
Thanks!

Actually, the hard chrome faced ring sets may take a little longer to break in, but are typically longer wearing than other types of cast rings. You might use a little oil at the beginning, but should have good compression sealing for a long time thereafter. The oil control rings are still stainless steel rail type, IIRC.

bore finishing
actually the bores are supposed to be finished finer than that. They are good rings for like dirt track racing. From what I here they take forever to seat and burn oil. Atleast that was the research that I have come across.

400 grit stones work fine for those.
People use those rings for an incredible number of engine rebuilds. I've used them myself a time or 2. No problems, no excesively long break-in, none of that. Proper assembly goes a long way toward insuring against such things.
