Default deep scratches on passenger side intake ports

video of heads
I have never seen anything like this. I still have not removed the heads to see if there is any damage there, but any ideas what could have caused this or how bad it is? They are on 823 heads.

Those look like casting marks. Identical in every port. They have been there since they were cast.
