Two thoughts:

1) Depending on the "depth" of the rebuild, their will be a break-in
time of having things seat, adjust, wear, etc. before max numbers will
be registered.

2) Based on personal experience, vacuum gauges, even supposedly "name
brand" ones can be way off the mark.

Start the engine, properly break in the engine, asses the engine on a
"seat of the pants" basis; if everything's cool then don't worry about
the vacuum numbers.
