Smog removal help

[MustangGT95]

Is it possible that an f150 motor does not have the place to inject air in the back of the heads? I went and purchased 9/16'' bolts like the uninstall explained but I cannot find a hole nearly that size. It did have the tube ran back there but I can't find the place for the air to go into.

This motor is a roller motor from an f150 I believe. I assume its possible that it doesn't have air injection?

I suppose it could be.... really doubt it. If you are looking at those heads and there are not holes, well then... FWIW, IIRC, the threads in the holes in our heads are 5/8-11. I used bolts to plug mine before (which makes them easy to remove).
