Vacum Brakes

[BARTGN]

I have Master Power Brakes kit in my 86 GN, work great. I am collecting parts for replacement engine. I want to go roller cam . At what point does cam size,timing lift, duration affect vacum for brakes?

How big do you want to go on the cam? I'm running a 208/208 with vacuum brakes. No problems.
