Sweet set of complete, genuine Harley-Davidson big port Knucklehead cylinder heads. Made in Milwaukee, Wisconsin, USA. Recently rebuilt, these came off a running engine. Rocker boxes are dated (C-1) and (I-1). No chipped or broken fins, no broken or repaired diving boards or rocker tabs. Spark plug holes are tight. These heads have been converted to run Panhead cylinders, but this may be reversed easily. Or, run the stronger Panhead cylinders. The rear head is chipped near the intake port where the head bolt goes into the head. The bike was running this way, but this should be repaired. Rocker tins are reproduction.
