Trying to get parts together for my bbc build. I plan on using N20 on it, I'm thinking 250 Max. The Probe pistons I'm looking at come with a moly top ring set. Ive been reading and finding all kinds of different ring opinions. Seems like Hell fire rings are a good choice, but do I need rings that good. Or will the moly rings do the job? I want to do this right the first time but I don't want to go broke in the process.
