The 820 single ring pistons that K Precision was selling, is the ring chrome, or is it a standard steel/iron ring like a normal 820. According to Dave Bonbright, you should NOT run a chrome ring against a chrome bore. I'm hoping these pistons and rings were meant to retrofit an earlier 820 so you can upgrade the engine. )f course, you can run a chrome ring OR a standard ring on Nikasil, but not on chrome bores. Any thoughts? Thanks. Ted
