Polished LS6 Heads??
I am getting my LS6 heads ported. Does it make a difference if the heads are polished? If so, what is the difference? Is there a big cost difference?
thanks for your help

Polishing makes them look nice and shiny. Apart from that not much else. And given you should never see them again, not much point.
Its shape that matters for airflow.
Some claim that a polished exhaust port ( and possibly chamber ) will lessen the chances of it sooting up with carbon deposits, although I dont think it really makes any difference.

Someone know for sure and have some proof.

no i agreee that polishing will reduce turbulance. look at an airplane, my father used to wax and polish his airplane and showed me once the difference between dirty and clean on the Gps. there was a 18-20 mph increase when it was clean compared to when it was dirty. now think about that dirty paint is obviously smoother then bare cast metal, so i'd agree that polishing will decrease turbulance.
