Perhaps it will help if I post pics of my airplane. It is now sitting on my loft without the prop. As you can see, I have already opened up the cowl all I can.
Now please dont say that irrespective of how open it is, it required more cooling. Remember, I have tried it out without the cowl.

Great now we can see what you've done.
Some would argue that there is not a cooling hole, but there is enough of a cutout over the head that you should not be having problems.
So it's back to what is causing all of the heat issues...?
What is the ready to fly weight of the plane?
You may have posted it before... but if you would please post it again.
