Master Cylinder selection?

Finished the BBP manual disc swap on my 67 Valiant. Now to the rear...Going with a Ford 8.8 with disc. In keeping with manual brakes, what master cylinder did you/anyone you know, use? I plan to use a Wilwood adjustable prop valve and have the 4 to 2 bolt mount adapter for using other brand masters...If needed. Any successful answers would be appreciated.
