I can't see where this has been covered before. Anyhow, I just sent in my heads, pistons, valves and bearings to be coated. I'm getting two kinds of ceramic coatings. One is a thermal barrier coat, applied to the piston top and the combustion chamber and valve faces. This helps keep heat inside of the engine. If the heat is absorbed into the metal at this point the energy is lost.

The second kind of coating is a thin film lubricant on the bearings and piston skirts as well as the valve stems. I could have done some more items, but I thought this was enough for now. The idea is that I'll not only have more lubrication for engine protection and longevity, but I'll have tighter tolerances, allowing me to use a thinner oil grade. I'll post back on my progress.
