How long they last is a big consideration. Also what's available at a reasonable price plays a factor in my world. Some of the metric rings are custom for some popular Pontiac bore sizes from one manufacture (I should say re-seller) and a similar set is considered a shelf item with another and it sells for almost half the price.

Normally I would totally agree with you. But this one engine, this one time, I'm taking the cost factor out. I want the best, and I'm willing to pay for it and wait for it if needed. It's already been a couple years since I started acquiring parts. I'm down to needing pistons, rings, lifters, rockers, gaskets, and just the little stuff. I've got billet mains, forged crank, Oliver rods, custom cam, intake, custom built carb, and CNC ported heads sitting and waiting. I still need to clean up the block and verify that the bores will clean up, but pretty confident they will clean up just fine at 4.145". There's a lot of rings available in that size. This is the original block out of my 69 Grand Prix that I've owned for 38 years. I took it apart and it still had the original pistons. The only reason I took it out (about 25 years ago) was to put in a 428. Time to put the original back in.
