With the dry compression good I would think the valves are ok. The rings are probaly not fully seated yet as indicated by the wet compression. Regarding the lack of vacuum & the hesitation I would check the timing at full advance⎮-37 degrees at 3000 rpm] & the cam timing. If the dots line up on the cam & crank gears, then verify that the cam is not misground. I've heard of this happening on some aftermarket cams. By the way if you are using a newer formulation of oil be sure to find a zinc additive as they have removed most of the high pressure additives from the latest formulations. Oils used for diesel engines still have the zinc in them so use one labeled for diesel engines. Lack of zinc can cause rapid cam wear[especially flat tappet cams],even on a new cam. To check the cam timing you will need the "cam card", which tells you when the intake & exhaust open & close in degrees. Also, what is your vac. reading at idle? Good luck!
