no difference. Have them surfaced but ONLY as much as need be to make the true. Also if they have a lot of miles on them you'll probably need t least new exhaust valve guide seals. I'd recomend replaceing all the valves and springs. You will want to make sure to work with your machine shop in getting the spring seat pressures set properly. Tell them how much boost you plan to run and set them up accordingly or you will have valves floating into pistons. To be sure you could call Crane and tell them how much seat pressure and how much over the nose pressure they want to see for the amount of boost you are running.
