what line go's where?

OK let try to element any rants the might occur.
My 67 barracuda with a 15/16" master cylinder, has a manual disk/drum brake swap which had a proportioning valve like in post #2, now has new line and distribution block/proportioning valve like in post #1. I bled the lines and don't seem to have any air in them, but they still feel like I never bled them, and still have to pump several time to build up peddle pressure.
In bleeding the rear brakes the peddle would go to floor when bleeder is opened on the drum. The fronts when bleeder is open on caliper plenty of fluid would come out under pressure but brake peddle wouldn't travel to floor. Not sure what the problem is, line are correct only difference the type of proportioning block used. What to do next?
