Re tube bravo, does it need to be biased

I want to try different, but matched EL84s on the output side, do I need do anything other than switch them out?
Do the 12ax7 tubes need bias changes when switched out? I take it they don’t have to be matched, any recommendations on tubes for the clean channel, a good tube for metal on the dirty channel, where are which ones located.
