Message	The cams work without larger valves, port work always helps. If larger valves are installed, work must be done to un-shroud the valves. Just installing a larger valve will hurt the flow , this is because it is harder for the air to get around the valve without de-shrouding it. You can go backwards if you do not know what you are doing. Either way, opening the valve higher and for a longer time, will move more air, and make more power, provided the valves are opening and closing at the right time.
