Proportion valve and Residual valve?

I think this will depend on your individual situation, so far as metering / proportioning

My setup is 73/ 74 A body front disc conversion on my 67

Rear is a factory Versailles disk brake axle.

"I took a gamble" and simply tried the factory manual master. It works well. All I did was puncture the residual valves. I have no proportioning or metering of any kind. It just flat STOPS
