noticable with a straight edge? if they are not to bad you may try some red rtv. or using 2 gaskets. did they leak or are you just skeptical of installing them simce they are warped. also if its not to bad and you have a good hand. you maybe able to sand them flat? just trying to throw you a few tricks.
like i said the best way would to be just call.
