"I did these mods to all the outside cylinders. The pictures are not great but I also bent around the bottom of the cylinder and boxed them on the outside to prevent leakage."
Ron also attached some really helpful photos. One is excellent in showing the suggested slot and deflector on cylinder 5 by the alternator as well as the kind of attention to detail required to get best use of cooling air and reduction of cooling air. Nice work that controls the air flow well.
