Lifter roller surface

I am getting ready to put a new cam in the 302, and in that connection took the lifters out to make sure they were OK. The engine only has about 50k miles on it so I did not expect any problems, but the surface on some of the rollers looked a bit strange see the attached pictures.

When I run a nail across it is not possible to feel any groves. Is this normal and OK to put back in and run with a new cam?

If you're putting in a new cam, I wouldn't run those. At roughly $125 for a set of equivalent Ford Performance hydraulic rollers, I'd replace them.

I have to agree. Those marks look they've been wiping a bit on the cam shaft. Mine didn't look anything like that.
