port matching the intake manifold?

See this totally make sense to me especially in a fluid dynamics sense. I wanted to post the question because I've never done this before and wanted to make sure it was okay to do. Still new to the performance tech stuff.

What ever you decide to do - make sure the intake port exit is not larger than the head port inlet - major turbulence if it is.

Yeah I understand that if there is even a small lip there would be turbulent flow. Same reason I"ve heard that your carb base should match closely to the top of the manifold.

More comments or suggestions are more than welcome. I'll learn whatever I can.
