Dual quad info

Maybe the FABO engine gurus can answer this question... if the cylinder head ports are larger than the intake manifold ports, like is showing in Steve's post #60 in this thread, is it really that big of a deal?

I mean, obviously having the intake and head ports match would be better, but with the fuel / air mixture being drawn into the cylinder head's larger intake port it's not like the mixture is running into anything. I can see how a large intake port and small head port would be terrible, but when it's like this situation is it really that bad?
