Well, I guess if somebody wants to go to all the effort and expense to put something on the engine that will make the underhood temperature go to extremes, and then spend MORE money, time, and effort to correct the first blunder, go for it! I'll stick with what was engineered to work, and did it well for decades, the cast iron manifold.
Different strokes for different folks, but it seems to be sort of foolish to create a problem, then try to correct it, when headers are the answer to a nonexistent question!
