There is a world of difference between the temperature ranges of a valve cover and an exhaust manifold. In the olden days, we couldn't stop MC pipes from bluing from the heat, even though they were double-walled. I coating that would survive that kind of heat would be a special coating indeed.
Oh, we did used to paint them with hi temp paint, but that needed to be re-applied at times.
