cam markings

The cam bushings and inside of the n47 were as dark as the timing sprocket. I used concentrated Simple Green and concentrated dish soap together with an old toothbrush to clean things up. It took a while, but I think it was worth it.

All of the cam bearings have different casting marks, and several have different hand written-ish markings on the concave edge where the head bolts would go, and for this reason all of the photos of them.
