Very likely. Machine tolerances are way better than they were in the bad old days, and that goes for reputable aftermarket parts too, not just OE. If the rings were the right ones for your application, the chances of getting a tight one are someplace between slim and none. Tight clearance is what can really hurt you in terms of wear or failure. Loose tolerances can hurt too, but generally only in high-compression or boosted applications. For an NA application, the effect of loose clearance will generally be minimal-to-none.
Yeah I'm mainly worried for tight clearances, thinking on buying an ISR rad to help with cooling so nothing heats up too much in there.

If you want to take precautions, an oil cooler will serve you better than a bigger radiator. The pistons, especially the crown areas, are cooled primarily by oil coming out the spit-holes.Akuhyo wrote: ↑Tue Mar 02, 2021 8:41 amYeah I'm mainly worried for tight clearances, thinking on buying an ISR rad to help with cooling so nothing heats up too much in there.

I'm just hoping the gap is either stock or at least big enough to where the ends wont butt when heated up. This is my first car & first engine I've ever rebuilt which is why I'm so worried.
Hmm yeah I will probably get an oil cooler now.VStar650CL wrote: ↑Tue Mar 02, 2021 9:27 amIf you want to take precautions, an oil cooler will serve you better than a bigger radiator. The pistons, especially the crown areas, are cooled primarily by oil coming out the spit-holes.
The chances are lower than low if the rings were the right p/n, tolerances on rings from any reputable source these days are in ten-thousandths. The primary risk is of a mis-packed product that was oversize.
This is a late reply but by p/n do you mean part number? I didn't get the rings from an OEM nissan supplier but the rings were from DNJ rock. It's starting to become time to finally start my KA, I'm just afraid those rings are gonna butt ends.VStar650CL wrote: ↑Wed Mar 03, 2021 5:34 amThe chances are lower than low if the rings were the right p/n, tolerances on rings from any reputable source these days are in ten-thousandths.

Yep, p/n is part number.
