Brake plumbing for LS1 disc swap

[TechNova]

I have read thru numerous articles on this swap and have swapped the mechanicals over on my 69 Nova. There is not alot of info on the plumbing.

Do I need a factory style proportioning valve?
I found one post that said I need a disc/disc valve then an adjustable for the rear.
I am using an adjustable valve for the rear.

The Camaro I am also working on does not have a prop valve that the front line go in to. It has Baer brakes and DSE master.
The front line comes out of the master and tee's into the two front lines. The rear goes to an adjustable valve. The brakes seem to be working fine this way but I have only had the car up to 30mph on my road.

It would be easier and cleaner if I did not need the factory style prop valve.
