Very few kits have a brake servo and not seen a BEC with one.

As above.
A servo is usually connected into the inlet manifold between throttle body and engine,I can't picture how you could get a decent set up with the bike carbs as they sit directly onto head with no inlet manifold.
What car are you converting?

You could tee all 4 of the vacuum ports in each inlet together and then run 1 pipe over to your servo which would give you the best bet of it working. As others have said though most people don't run a servo
