I have a 80 corvette and they always had cooling problems. I built small block 400's 600 HPand had real cooling problems. I built a 468 650 HP and had bigger yet cooling problems and on all of these engines. I burned plug wires mostly the spark plug boots. I built a 522 750hp and I coated the pistons, the combustion chambers, the exhaust port, and the face of the valves with a ceramic coating called CB2 from a company called Tech Line Coatings. My headers were coated with Black Satin. My cooling problems went away and I have yet to burn a spark plug wire because of the headers. The finish is really tough. Has anyone used any of the coatings available on there Big Dogs. The princible is to keep the heat in the chamber. Heat is HP. I did it to eliminate heat soak problems. I melted my poly motor mounts. Looked like melted red candle wax. What do you think?
