IIRC, my Q-jet originally from a 4.3L V6 (17086047) has no bypass orifices. So I would say to block them off entirely, then you can add bypass air only if it's needed. If your cam requires a lot of initial timing you might need some bypass air to keep from opening the primary butterflies too far. The bypass air is similar to drilling holes in the primaries.
