1971 340 Build - Choosing piston rings dilemma

I like the mancini Racing engine "kits"... Kits A & B are basic ....

Thanks for the reply and the links. However I don't need those things, I already have several gasket kits, TC seal, the bearings, The KB pistons, engine freeze plugs, TChain etc. It's just the rings and conrods I need now.
