I have manual brakes on a 72 Duster, drum in the rear and Strange disc brakes up front with a modern style master cylinder with the 2 plastic caps that twist-on, and all brand new brake lines.

Do I just fill the master cylinder and let it gravity feed the lines over night, and bleed them the next day? Or is it more complicated than that?

My Strange front discs are the 4-piston type so I have to bleed the 2 on top and then flip it around and bleed the other 2.
