do a ceramic coating on exhaust headers/pipes that the racers use to
keep heat out of the engine bay.  I'm thinking about using it in my
installation.

We have used this service for years with good results.
Have also applied it to tops of pistons.

David Carter asks:

If it has been applied to tops of pistons (what were the expected and actual
benefits?), then could it be applied to 3 sides of each rotor in a 13B
(maybe reduce heat loss through rotor faces to oil being squirted into
insides of rotors, and thereby reduce the heat loss through oil system,
reduce oil cooling requirement, get more power out of engine and less out of
oil cooler system)?

I think Mazda tried it on the Lemans engines and it did not help
much. The difference maybe the heat conductivity of cast iron verses
aluminum.
