Open headers = warped valves? I have the QTP off-road Y-pipe with dual electric cutouts after the headers and someone told me that running open headers will warp the valves in my heads because the headers let in cold air (I guess when decelerating?) He said that was why race cars always have those flaps at the end of the headers. Is there any truth to this?

Don't sweat it. Look how many big drag cars run open headers.
