It appears the rockers were making contact with the heads and left a grove. Is this common? I'm not sure what rockers/cam/pushrods the previous owner was running. Once I get my valvetrain installed and mocked up, I will look for contact.

Is this anything to worry about?

Totally normal. Nothing to worry about.
