Does that intake have an open plenum or milled divider? I have an old 427 corvette with mostly L88 pieces in the motor including the open plenum, dual plane L88 intake. They (GM) ran staggered jetting in it to better adjust the air/fuel mixture for differences in runner flow. Each barrel in my Holley has a different jet size. Not sure how common this might be in other motors - Seems to be dependent on the intake.
Or could be as simple as a partially clogged air bleed as you mentioned.
