As George suggests, rings are the prime suspect if you have different wet/dry compression readings. I've never heard that this would be normal for a fresh rebuild. Of course they do say you need to take it easy on the motor for the first several hundred miles.

Did you just put in stock rings? Was there any machining done? I'm wondering if the rings are too small for some reason - either due to cylinder wear or machining.

I've read that poor vacuum is due to problems with the valves not seating fully or in the right sequence. Did you have a normal valve job performed?

Did you do the work yourself or pay someone to do this?
