Re: Cylinder Head Exhaust Ports
Not enough carbon there to worry about. If you take the time to clean it, it will look about the same in a couple weeks. It looks very normal.
As Ron said, if you were to clean it, rotate the engine so that each exhaust valve is closed on the port you are about to clean! Do not want to knock that carbon into the cylinder through an open valve.
