I remember the same thing as Niagraglenn said. Before the new intake, no screw inserts by the plugs. It does look like they are for coil on plug. My intake cracked after I jacked the motor up and forgot to take out the strut tower brace. I thinking why is this motor not going up more and the whole car is. So the intake was taking the weight of the car (or some of it). It had like 95,000miles on it then. After I finished putting the headers on, the intake cracked the next day. Somehow I think holding the weight of the car had something to do with it. Ford replaced the intake under the cracked intake program (fortunately the crack occured in the correct spot).
So check for those mounting screws and you will know. Also, check Randy Stinchcomb above for a manifold. His prices are great and he will know all the options. Cool to have a Stang in S. Africa!
