Identifying a Mk4 or Mk5 cam

Can anyone tell me the visual difference between a Mk4 cam and a Mk5. I know the degree specs of each, but have 4 cams on my bench in front of me but wish to pick a Mk5. If possible a picture showing the difference in cam lobe shape (if any) would be appreciated.

Welcome to the forum Napolean.
The MkV has less overlap than the MkIV as you probably know and so the cam profile looks sharper in the MkV.


The MkV shaft is on the right.

Thanks Peter, that is just what I wanted to know.
