These will only work if you now have the 1.6 ratio rockers now and also they are pedestal mount, (meaning they are held on with a non adjusting bolt). I'm not sure how your rockers are on now but AFR heads normally have a stud mounted rocker. If in fact your rockers are the pedestal mount now then yes they will work if you are now running the 1.6 rockers. Also you may need to buy a shim kit to make sure you have the correct amount of gap between the top of the valve and the roller. Hope this helps.
