Thoughts On This Cam Image?

Hi,

I was hoping to hear some thoughts on this cam picture. It is a regrind, but I am not sure what to make of the lobe markings? Any thoughts would be appreciated.

Thanks
James

The oil film broke down.

What do the rockers and rocker shaft surfaces look like? Post some pictures. Preferably the hardware from those two lobes.

That info is needed for a better answer.

Thanks for the replies.

I do not have any more pictures. The cam is for sale.

Is the repair the same cost as a regrind?
