Explanation of where cam# is located.
 

The 5-digit # is located right between the exhaust and intake cams of cylinder #2. Rotationally speaking, it is lined up exactly, with the lobe peak of the #2 intake cam (4th cam back, on the shaft). Oops, this should have gone into the n/a forum, as it has vastly larger readership.

I forgot to mention, that if you remove the 3rd plug on the cam tower, and orient the shaft so that the #2 intake lobe is pointing straight up, the # should be right there.
