The all drum configuration requires residual pressure (about 10 psi) be retained in the system. SOME master cylinders sold by vendors (advertised as drum/drum components) do not have the check valves integral to the cylinder.

Those w/o the integral check valves may still be used. Separate/external 10 psi residual pressure valves are required; one for the 'front system', one for the 'rear system'.

Proportioning valves are not required (and serve no purpose) on the all drum systems. The approx 60%-40% front/rear brake force distribution is accomplish by using wider drums/shoes in the front. Hydraulic pressure is uniform throughout the system.

Just info you may already know.

Also, the wheel cylinders are different sizes, the fronts are 1-1/8” and the rears 1”.

Did you find the firewall studs are too short?
Nothing is easy.
