Couple of possible issues here.

One, is that the flywheel is not balanced.  When that weight ring
was cut off, it should have been rebalanced... optimally with the
pressure plate attached.

Second, is that the cam timing might a little off...sounds like it
might be retarded a tooth.  This, on top of a more aggressive intake
cam, is probably affecting your vacuum.  Line everything up and
recheck.  Set the flywheel mark to TDC, then check the cam mark.
