I thought I'd just add a comment to this thread.

I just finished (last year) my car and was told by several people including a tech at Wilwood that you don't want to use proportioning valve which is mainly a way to decrease pressure to one system but that you want a balance rod type system that lets you simply adjust the amount of pressure to either set of brakes. Now that assumes that you have two master cylinders. One for the front and one for the rear brakes. I took their advice and the system works very well.

Just an opinion...
