Second is a 104 exhaust cam. Note the absence of the oil holes near the middle. Pretty much every other hole and pin matches though.



Third is the modified exhaust cam. I made a jig and added the oil feed holes for the cam advancer. During the drilling I thought for sure I would hit the plug sealing the end of the cam and have to re-do it. As luck would have it, it drilled to the center and cleared the plug.
