I'm using Deves piston rings in my new engine, they are kinda pricey compaired to some, but are US made. The company has been around for a long time. I know quite a few "old guys" that used their rings in their race engines for years and always had good luck. They have a two piece second compression ring which I thought was kinda cool, to help keep tension and I would expect hold better compression. I obviously don't have many miles on the engine yet so I cant give you any long term results.
