What dual reservoir master should I use to replace my single? I know that with certain m/c you need a proportioning valve and others the wheel cylinders do it, so that maens I need one that has the same size reservoirs? I plan on running the front brakes to one the rears to the other(just incase I want to put a line lock on it in the future), any help on the brake subject would be great, thanks.

If this a front drum vechicle, no proportioning valve needed. Use a MC from 67 up with drum brakes. If you have power brakes, same drill, use one 67 up with power brakes. If you converting to Disc front then use whatever P valve that will match the master cylinder.
