I cleaned it all with engine degreaser, simple green, purple power, rags ,tooth brushes, wire brushes, 3m abrasive pads, and coat hangers. i cleaned it all again with wax and grease remover. Then painted it with that low gloss black engine. I wanted to do the whole thing black but i was afraid that if i missed anything in between the cylinder and head fins that the paint may flake or chip. So i just painted them with the silver engine paint.
