Ported intake gain?

I have a Victor W2 intake on my 340” engine. Intake is as cast, no porting. Would there be a benefit with getting it ported? I do not port myself so I would have to send it to get done.
Who would be the person or place to call?


Take your time and do a nice gasket match and blend into the manifold 2 inches. Radius the top of the plenum and run it. Do a neat job and you probably gained 80% of what a well ported manifold gets you.
