 I had my JH header done. As my car is still on jack stands I can’t comment on real use, although I have heard from folks that it works as advertised. The key to the best possible application lies in giving them a new, unused header. New headers get the maximum coating inside and out and this would provide the best heat dissipation compared to simply coating the outside of a used one. I was told correct coating inside can only be done to new parts.
