Brake pedal is really stiff

Just an update...

Had all 4 drums turned. Bought new shoes, they all fit perfectly. Pulled all wheel cylinders out and replaced with correct Raybestos cylinders. Bought original Raybestos master cylinder. Bled MC, bled brakes and still have the exact same problem. Car is going to be taken into a shop as soon as I get some money for it. I'm fed up with this. It should not be this difficult to get a damn drum brake system to work correctly. There has got to be some kind of built up pressure somewhere because the pedal is stiff and doesn't want to be pushed down very far and the brakes are really weak. I don't even think I could lock them up if I tried. Yet when I bleed them the pedal will drop to the floor once I open the bleeder. It just makes no sense.
