they are at the back of the head facing the firewall. They are the biggist hole at the outside corners. There is a pipe that runs between them. As I have discovered, you can plug them with a 9/16" bolt and washer but it has to be cut down to like 3/4"

. If you are going to delete the smog pump then you will need a threaded insert known as a thermactor plug. They screw into the back and front of your heads. Put silicone on the threads to prevent any exhaust leak when installing them. The thermactor plugs you will use for the front (same as back) will go to make the head holes smaller so the accessories can bolt up like your power steering stud and one of your bigger alternator bolts that go through you alternator bracket. The back thermactor plugs you will use just block off and delete the smog equipment’s previous hookups. You can get them at a Ford Dealership - part # F4ZZ-6E086-A or you can buy some from Summitracing - part # TFS-51400265 and they run anywhere from $3 to $12 dollars from what I have seen. Summit has them cheaper.

On the back i just took off the pipe, flipped it around and bolted it back up again. Seems to have worked pretty well.
