Not really sure what you are asking here but the Livernois stage 2 or 3's work on a 346 but not the 3R. 3R has a 240cc intake runner and I feel sure the chamber must be opened up for the bigger bore. You can never go wrong with either AFR or TFS. Keep in mind if you go TFS you shouldn't use the stock rockers but they are fine with AFR's or any GM casting. TFS has a more affordable "as cast" head now that I have heard good things about but have not seen.
