Like .010 or more. I just usually recommend going to the 1st spec for spray and you can use the same gap on top & 2nd. Personally, I usually go to the 2nd step of N2O spec.

The ring 'flutter' I believe only occurs at extended high RPM was my understanding but doubt it's a problem/concern for most here, unless in competition. Great to bring it up though for sure!

Most top & 2nd rings have a mark on them, a dimple or color, that denoted top and 2nd, for ease of identification, and the mark should always face up towards the top of the bore.

For deburring after cutting rings a small, fine honing stone can be used, which is generally safer than a file, even a fine one.

Mm, sorry about the brain dump!

I know some of the specs for one of the greatest Pontiac NA builds ever. It had .050 on the bottom ring.
