I am under the impression that because of the center to center spacing of the two carburators decreed by the Edlebrock manifold ,you have to use two small individual air cleaners.
If you could put the teapots on the manifold (in the orentation that you will be mounting them) and measure the center to center measurment and post it,I can measure my Ford stuff and see where that measurement is at for comparison.
I"m pretty sure the Ford air cleaners will not fit on the dual quad Edlebrock.
You might also want to consider the rear carb setback and distributor clearance.
