All you would really have to do to know if it would fit the head (not the cat) would be to get the exhaust manifold gasket for each and see if they are the same. If they are, it'll bolt to the head, if not... well there you go.
where the fawk did you come in to play....re-read it please so i dont have to let you know that you dont know what you talking about.
