Yes that is a head bolt you can see through the opening in the intake port.

Run it.......i would be more concerned about the log in the middle of the port rather than cutting thru a small amount at the head bolt.
Not to discredit...but why is the area around the head bolt darkened compared to the rest of the port wall that was hit with the common sand roll?
