When I replied, I only sent to Chris Dimmock.
The first cam on the left is the earliest cam. It has a different oil =
pump drive gear. It won't work with most healeys as the gear will not =
mesh with a gear with more teeth.

I believe to be a very late 3000 cam. This one should have a part # =
stamped on the end. (I once saw a BJ7 cam with no rings and it had part =
#12B594 stamped on the end). The next two cams have a single ring and I =
believe these are early 3000 cams. The 4th cam with a 2 rings is a 100-6 =
cam. The 5th cam on the far right is not clear, it appears to have 3 =
grooves ... if that makes it a 2 ring cam then it is also a 100-6 cam.
