CNC Mill Mark Removal in Intake Port

Would going to a 2.08 valve help? I think it would only bring the throat to about 90%, which sounds too big still...otherwise it sounds like SM just has a program to hog out the ports for show, not go. Sounds like money would be better spent (at least on SM heads, and in search of higher end power) to get the non-CNC versions in the hands of an experienced person...or pony up for some better heads altogether?

Going to a bigger valve will help but its not really the right way because if those heads are like what I have seen the throat is chopped completely straight down. A 2.100" may even be the best "fix" but then the rest of the port probably won't play well with a larger valve. A smaller seat ring and some welding or good Belzona grade epoxy would be the right way. J.Rob
