Brakes for my drag car.

I have gotten to the point in my build where I need to build my brake lines.
I have strange 4 piston lightweight brakes up front and dana 60, 11 by 2ish.
I'll be using braided stainless flex hoses up front. 3/16 hard-line.
I will need to do the same for the differential.
My question is what should I use for proportioning valves ???
Factory 73 & up drum to disc
Or do I need to go a different direction?
I have fairly skinny tires in the front 28 by 4.5
Don't need most of my brake power up there when my big contact patch is in back.
What should I do, remember I'm asking for a drag car only I'm expecting 135 mph from the car
Run as much hard line as possible! Here is a pic showing how I ran a Tee to cross-over to the pass side. Then flex to the calipers from tabs on the frame. Make sure you avoid any binding or entangling over all movements when routing 'flex' lines.
