Jb1 brake help

I'm in the process of a junkyard 5lug swap and I'm running into issues with soggy pedal. I had 6 lug drums all around. Do I need to get a new master cylinder? Or can I get a proportioning valve to move more fluid? Im* going to do a detailed write up with all of the trial and error so it will become community knowledge for those stuck with jb1 brakes. Thanks folks!

You will need a master cyl and proportioning valve for the disc drum setup.

Is bore size relevant or preference? I'm looking at summit and there's 13 different ones to choose from. If I sent pics of my current setup would that help?
