Best rings for Nikasil cylinders?

What type/brand rings should I use for my 2.7 rebuild with stock, honed, Nikasil cylinders and stock pistons?

Hope you haven't honed them yet...

Read Henry's Schmit's posts on this subject in this thread do I need to hone this?
No No not a hone !!
It has been our experience that if you hone Nicasil cylinders the hone cuts into the Nicasil and because it is so hard that the new ridges are too abrasive on the rings. The rings will seat but they will not last as long as they would if the cylinders are prepped properly. We have had great results from Scotch Brite with soap and water. This breaks the glaze but doesn't cut the Nicasil. Don't forget to check for roundness. I've seen Porsche cylinders .004 out of round.
P.S. use only Goetze rings. Hastings in a pinch.
