I agree Diablo,but for a gimic to help sell motors it works pretty good don't you think? It's not a bad thing to paint the cylinders if it is properly cooled,that's why proper baffling diagrams are mailed with the larger twin cylinder engines,atleast they come that way with the engines I have received.I could have gotten my 106 with painted heads but I asked questions on the process and downfalls of it and decided not to go that route.
It sure does look pretty though and that does help sell engines. Again it's not a bad thing unless you are not properly cooling your engine consistantly.
