first off you have two cams one over each head. The best thing for you to do money wise is buy a set of 99+ PI heads and bolt them on with what ever else has to be done to make it work. You get great gains from it.

A cam would be a waste with the stock heads from the 96-98 GTs. Do like Spector said and get the 99+ PI heads, and then you can start looking at a cam later. You may want to try to find a set that's already been ported out a little if you still want to get a cam later.
