Yes, you can do the incision around the bill, remove the skull, but then I'd just cut half the skull away, pull out the brains and flesh. I do this on some birds, and will actuall flesh away the meat, but I leave the tendon that holds the lower bill to the jaw muscle. I then take the bill and head, and dust it completely in Borax. Let it dry for a few days, and re-build the muscle structure with apoxie sculpt. I know it sounds like a pain in the butt, but they are guaranteed to fit. The alternative (artificial head) is definately going to save you some time though. It all depends on what you're charging for the stuffers. I don't have any experience on stuffers personally, but for the most part, I think most times, the heads are just left in the bird. I know they don't even flesh the birds, but salt them heavily. I believe they use them for a season, and they may be considered trash after the season's end.
