Rustoleum is now making Engine enamels. Available at AutoZone here in OH. I had great results with it in Chrysler Red for my 67 Dart. I believe they had it in Mopar Blue & Hemi Orange as well.
I started with Duplicolor engine paint but was not impressed, especially after seeing it burn off of my exhaust manifold entirely within a week. I mean, it's made for that! Up to 500 degrees it says. I seriously doubt my engine got anywhere near half of that. Very poor gas resistance as well. Your mileage may vary.... Good luck
