what should vacuum be - 350 chevy, 9.3 CR, 236 @ .050

Im trying to slowly get my engine tuned just right.

With a 350 chevy
9.3 CR
236 duration @ .050 cam on 108LSA
base timing in the neighborhood of 20 degrees
what should me Vacuum be at idle.. at .. 1500rpm..?

trying to figure if I have a vacuum leak, and also if my vacuum isnt right, to adjust how rich /lean my carb should be..
please help, im new to the concept here


thanks
