Help my fellow a body guys

So I just got done doing kh swap on my 71 dart and havent got to try it yet feel like I have to keep bleeding it and its slowing getting better, I also switched to manual brakes from power brakes. Usually on a front brake swap and master cylinder shouldn't i get a pretty firm pedal with that setup it's also a 15/16 bore mc. It only gets firm after halfway threw, so just more bleeding it?
