Default What size

I have a 4 wheel disc brake setup going on the hotrod. I have the under floor pedal assembly with a 7" dual diaphragm booster. I will use an adjustable proportion valve and residual valves.
I want the corvette style master cylinder with dual ports but I don't know if I should get the 1" or 1 1/8" bore master.
What is the general consensus?
They are the same price.

Disc brake calipers need more volume than drum brake cylinders. I'd go with 1 1/8"...

Are residual valves needed for discs?

Discs or drums. Anytime the MC is mounted lower than the calipers or cylinders, you should use residual valves.

For my personal info, would you use 1 1/8" if it were manual 4 wheel disc ?

Sure, but pay attention to pedal ratio.
