I am having to pull the head on my truck because I have an intake valve that is making to much noise for my comfort. I am very happy with the power my truck has. But since we are pulling the head on it I am curious as to what everyone thinks would be the best mods to my head with my particular setup? Should I o-ring, fire-ring, port and polish, just slap some new valves in there, shave the intake plenum off? Please let me know what you think would be the best mods to my head to get more power but more so for reliability than anything else. Thanks!
