C5 and C6 master cylinders identical???

[Bowtiguy]

This one is directed towards a certain GM suspenion guru or anyone else who knows. I have a C5 vette master cylinder installed on my car to run my old C5front brake package. I just finished what I believe is the first C6 Z06 brake upgrade to a 4th gen F-body. Before I install a brake bias bloock to fine tune the system I wanted to know if the bore/stroke of these two master cylnders is equal. thanks.
