The bigger bore Vette (or whatever make) master will help, plus it's an added safety feature. If you do that you will need a slightly longer push rod to make it work properly. Adjustable push rods can be had from the hot rod suppliers (Summit, etc.) All vehicles, disc or drum, use a smaller wheel cylinder at the back, or a proportioning valve to reduce the chance of the rear brakes locking up during hard braking and causing a skid.
