Where to put 4 tubes on a 6 tube preamp?

I just picked up 4 really nice Amperex 6922 tubes for my 6 tube Sonic Frontiers line 1. I was wondering were to put them (and use the stock Sovtek for the other 2 inputs)?
Is this a good idea? or should I just pick-up two more Amperex tubes. I've heard it mentioned that you really only need two good tubes and that the other inputs are for bias control, but can't find any real info on this.

Pretty much everything you might want to know there including what positions and tubes are best.

BTW, I owned a SF Line 1 for a few years and used a variety of NOS tubes in it without any problems.
