    What can cause multiple valve seats to go bad? The valves aren't bent nor burnt but about 8 valves aren't seating correctly.

    Any help?

    A badly warped head as the head bends into a U shape, the seats and guides can move .

    The valves will grind straight, but will not seal on the seat
