I used a Strange 15/16" master cylinder with the line for the rears going straight back to the T-fitting and the line for the front brakes going straight to the line lock with no blocks or valves in the system. It stops straight and steady from over 120 with no lock up or pedal issues. I used one of Doctordiff's adapters and pedal pushrod. I am still using the original manual drum brake pedal assy.
I was going to use the Wilwood adjustable block but my car stops great now so why waste my money shruggy
