    98 vs 99 head catera

    I see in my searching for a used head that they use a different part number for the 99 head. My question is what changes did they make and can I use a 99 head on a 98 catera?

    Thanks

    No need to be gross. Very few Catera owners visit this section. They focus on the Catera Forum. I don't have an answer for you re: your problem except that Patience is a virtue.
