Question on port matching

mbaird said

By "flange " do you mean the carb mounting base to plenum ? Or the short turn of the runner ?

I see the intake manifold as 1st the flange the carburetor bolts to.... just below, the bottom of the flange.. is the short turn 'its upside down' and just below that..the open area is the plenum from there the runner mouths/runners themselves.
