Do I need to run a prop. valve with my new set up??

[FLYNAVY53]

Vehicle: 1972 C20 3/4 Ton 2wd Suburban (daily driver street car)

Original Brake System: Power front disc (single piston), rear drum with dual master cylinder

New Brake System: Factory booster with Baer 1 1/8 "Remaster" master cylinder
Front Wilwood dual piston calipers (6.28 piston area/ 3.9 pad volume)
Rear Wilwood dual piston calipers (2.46 piston area/ 3.9 pad volume)
5.6:1 factory pedal ratio
All new 3/16 steel brake lines with -3 fittings throughout

My question is, with the new system, do I need to run the adjustable prop. valve available for the Baer master cylinder or does the difference in position area front to rear account for proper front to rear brake bias?

I realize that may potentially be a dumb question, but I figured Id ask before I go through the trouble of plumbing the prop. valve....the system is complete with the exception of the short lines coming off the master cylinder that would potentially include the prop valve.

Thanks,
Greg

I would think you'd need a proportioning valve of some sort. I've got the brass one that does this automatically. I also am considering taking the power brake booster off and putting on a larger diameter Master Cylinder with a manual valve.
