Doug,
Read my reply above .

I have even run the car with the inner headlights removed - and it makes NO difference.

As I have not increased the air flow through the engine (I've just made that airflow more efficient), I don't see the need for your mods at the moment, but I won't rule it out until I confirm full load temps at Bedford. However, at this stage, the road temps are lower than they have ever been, so it works exactly as I intended it to.
