no, you do NOT need head for the stage 1, i would suggest you upgrade the valve springs however, as at stock levels they already have valve float
also, no premium gas will be needed and you dont need to tune the PCM.... however, as with all mods, you will get more power out of tuning the setup
a reputable mechanic should be able to do a cam swap with no problems but the engine does have to come out or the subframe dropped to get the old cam out and the new cam in so when you do that it would be a good time to take care of any other problems you have
