Which Preamp Tube is most consequential: Input or Gain

I've just gotten a pair of 1950s Tung-Sols for my Schiit Freya to replace two of the stock Russian NOS 6SN7. I will try them in both positions, but is there a typical position of more impact in terms of rolling preamp tubes in the input vs. gain positions? Thanks for any experience you'd like to share.

Place your best tubes on the right hand side forward and rear

Why would you install the new tubes in the right channel gain and cathode follower?
The new tubes go in L and R channel, either front or back.
Front would be the gain stage, unless Freya has an odd design.

@peterf6 , ok thanks for your comments. That’s a different layout than preamps I’ve owned. Typically, tube circuit is L R in front. 
And of course, Ralph (atmasphere) is correct.
