Result!
With this installation I was able to keep my headrest at normal height. My real question was if I need a second method for securing the camera. When I first started looking into this I read a few SCCA regions that had rules about in-car cameras. Most required a second method of retention. In many cases they allowed the camera strap to be that method so long as it was securely mounted to the camera mount as well.
What does the SCCA or OMR require?
EDIT: This is all I could find...
"3.3.3 Safety Inspections
B. Inspection Requirements
1) All loose items, inside and outside the car, must be removed. Passenger’s seat back and squab shall be secured. Video cameras, if installed, must be securely mounted to withstand loads from driving maneuvers. The camera may be installed either inside or on the outside of the car. In either case, its mounting method and position must not interfere with driving or pose an additional hazard to driver, passenger, or course workers."
So I guess once one of the tech inspectors yanks on it to make sure it's secure then I should be okay?
