F4ZZ-6E086-A thermactor plugs...they are a threaded insert.

The plugs from Ford are probably the "right" way to do it but I have found that they run like $16-$19 each from the dealer. I have discovered that a 9/16" x1" bolt and washer do the trick just fine for about $1.

I just cut the pipe in half and flipped it around. Blocked the holes nicely.

You can definitely do any of the above, except the bolt size is actually 5/8" and you will probably have to find a longer one and cut it down.

On this topic, what do the holes look like, where are they at on the heads and what purpose do they have?

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.

And what happens if you don't block these holes?

You have a haenous exhaust leak.
