I remember seeing something years ago about quick-change jets that were accessible through plugs in the top of the fuel bowl, so no gas escaped when changing them. That had to have a right-angle fitting of some type screwed into the metering block too. Is there still such a part?

Must have been a right-angle fitting with male 1/4-32 threads to screw into the original metering block, and of course female threads for the stock Holley jets.

What I recall is something like the quick change float bowl but with the plugs in the top, and the jets oriented vertically in an adapter fitting. Maybe I'm just conflating different memories Anyway once I get my jets set close enough for street fun I probably won't need to change them very often, if at all.
