During my next engine refresh, I plan on ceramic coating AND wrapping my headers and I'm also adding air extractors to my hood. I already cut my fenders to make the Trans Am air extractor functional and when the dual Spal fans are full blast on my C&R radiator, it's amazing how much heat comes out of those vents and the bottom of the car. Just a tremendous amount. Stop and go in traffic when it's 120f outside with the Vintage AC running is a lot to ask.
Secret I found out when getting my headers recoated - some shops will coat BOTH the inside and outside. Figure that cuts down on heat even more.
