Thermal coatings

[Bruce]

Just a point to consider,  the edges, and last threads of the spark plug
might be the hotest spots.  Reducing the surface area of the chamber itself,
makes a chamber alot less prone to detonation.

I am just watching this one, but I believe Hooker Super Comp headers are
coated both inside and out. I've also read on the DIY kits, most enthusiasts
just don't take the time to coat the inside.

Really, if the coatings do work, I would imagine it would be very important
to do the inside also, as this would lower the actual temp of the metal
pipes, reducing fatigue.

The one I'm really interested in (besides turbo exhaust manifold and
turbine) is coating the exhaust valves, as they are the single hottest part
of the combustion chamber.
