Is intake manifold port matching worth it?

You will get dozens of responses, and the same amount of opinions on the subject !

Here is one....

"On the surface, this would appear to be an important part of any high performance engine build.
This would seem especially important when the intake port opening is smaller than the manifold.
This is even supported by flow bench testing where any obstruction or sharp edge at the port inlet results in major flow losses."

"But this is one situation where the flow bench can lie to you."
