C5 and LS1 F-body Master Cylinders

[EFI69Cam]

Is there any difference between these two other than the reservoir and casting (the lines come out on different sides)? The internal bore diameter stroke etc? are they different?

I am changing from C4 front and LS1 rear calipers to C5 calipers all around. Should I use the C5 master? What about the C5 proportioning valve should I use that as well?

Thanks for any info.
