You will need some short bolts , i think there 5/8 coarse thread ? . I use the idler eliminator pulley kit from the 5.0 stang . You may not need it but it helps keep the belt running strait at hi RPM .... Lew

The holes with the smaller threaded insert are the front of the head where the accesories bolt on and these inserts are blind meaning they are plugged. The rear of the head will require 5/8 coarse thread bolts or cap screws, I bought mine at a local hardware store and added copper washers to endure a good seal.
