What cams are these?

[jed344]

We are currently working on a customer car and the cams that came out of a used head that is going on his car says I and E on them and 480 on the ends of both of them. That is all there is for markings on these cams. Did they ever mark stock cams in this way or do we need to measure the lobes to tell?
