I think maybe you could change what port is doing by a small margin with surface finish.

But most of the time a rough finish will make more power than smooth.


thank you for your response. bow with a slight "tootsie roll" cleanup, would anything be gained, other than a "good look" to the port ? if i were doing this, it would make me feel good just going over the finish with a 60 or 80 grit roll.
