This picture shows the autopsy technician pulling JFKs scalp into position for a photo. If he left go the scalp would fall back and you'd see a large hole there.

That is not a photograph. Re-read the caption.
 

If, as some people contend, there was a large hole on the right rear portion of JFKs head and a corresponding small entrance hole at the hairline area above the right eye ...

I have never heard anyone state this before.

Clint Hill said there was a large hole at the back of JFKs head.

Exactly. I think about 40 people said this.

  When considering head movement relative to a shot striking the head, You also need to consider another shot also striking at the same general time. Also, remember that Jackie has ahold of JFK's wrist/hand and is pulling Downward and possibly toward herself in order to see what JFK is clutching at in his throat area. Also, for all we know, JFK is coughing or choking at the same time all of this is happening. That shot or shots is Not striking the Rock Of Gibraltar. There is movement/motion involved also.

That's a new one on me! JFK is just coughing in the Zapruder film 

And what was the head shot, a migrane?

The car and JFK are moving forward when the bullet(s) strike his head and he's being held erect by the back brace /wrap.

The bullet doesn't need to throw his head back to create the effect just stop his head's momentum while his body and the limo continue forward. IMO
