    What size valves come stock in a '80 185s vs. '83 200x?

    I'm just trying figure if the 200x's have larger valves. Does anyone know if they are the same length as well?

    If they are larger, is there enough 'meat' on the seats to open them up?

    as far as I know you can just bolt them right in and you can use the 200x head as well.(look on ebay and you might find one of those heads that are ported)if you want power then go with the wiseco high compression piston kit.
