I've seen this post before, but now I can't recall the recommendations. When you order the AFRs, you kind of expect to see your reflection in the ports, but the reality is they're not polished, and still have very visible, even, ripples in them from the CNC process. What is the consensus on this, does it help, hinder, or have no effect on the flow? I know some turbulence is actually a good thing. Is it worth polishing or should I just bolt and go? It's a 351w for street use only, split-pattern cam just over .500 and around 275 duration.
