I don't think a positive seal is the issue, since there is air bypass at the throttle adjustment screw anyway. The issue for me was that the butterfly would hang up on the lip of the worn area, making it difficult to "feather" the gas pedal. I pretty much took care of that situation with light sandpaper.
