Valve job vs port and polish
I always see port and polish as the first thing done to heads so i was very confused when a reputable head guy told me valve job is where you see the biggest improvement. I know the ls3 heads flow very well but I don't want to get screwed here. He quoted me same price for a 3 angle valve job and cleaning out the bowls vs p&p. Which makes the most difference? Not doing both. I'm going medium cam, no intention of blower if that makes a difference.
with these heads i'd say the Valve Job. i'm doing a small cam and i did stage 2 prot/polishwith valve job LS3 intake valve and Manley Stainless Steel exhaust valve work done by Land Speed contact Brett he will know for sure. and will probably explain why also . Good luck.

the only thing that I would say is make sure that you use LS3 valves ( much lighter)
