Carb recommendation

Ok. Thanks, Learned something new :) Always considered smaller primaries being a spread bore. So, now that we have that straight. Recommendation??? I will check on the cross over gasket, not sure which set I put in when I rebuilt it. Either way, still looking for a new carb.
When you mentioned you had an Avs told me enough that it’s the same as a Holley flange.
A Holley will bolt up with a minimal of fuss.
