Ls1 Proportioning valve help

I just bought a 99 Ls1 rear to swap into my car basically for the brakes.
I found some confusing answers about the brake pressures for disk brakes.
I am trying to get all the parts I need to do the swap. So my question is do I need more or less line pressure to the rear for the drum to disk swap.

I would to be able to adjust it with an adjustable prop valve but from what I have read it seems like I need to replace the whole valve.

It doesn't need to be easiest fix, I want to have the best results from this swap.
So whoever has had good results what did you use?
