I rattle can painted mine, cured it in the oven when the missus was gone.  Duplicolor satin black high temp.  gas spills were not an issue. 
I prepped the ufck out of it before paint went on.  aircraft stripper, brass brush, pressure wash, ....repeat....acetone...etc.

It was paint, not powder coat.  I would not use powder coat on the engine, as it makes the coating thickness too big and becomes insulative.  Not good for an air cooled engine that is required to rid heat from the surface.
I never knew exactly what paint Honda originally used though.  I do know it was very thin, and aluminized on the silver engines.  Powder coat didn't really become popular til about 20-25 years ago when the EPA and other agencies were mandating low VOC coatings, and low emissions from painting facilities.  This made paint products so expensive that powder coat could compete and be profitable.
