Head Bolt, Stud Torque Tech Tip - Importance of a proper washer - Interesting

pics as promised. I think I'll just knock the burr off and live with it. The SM stud kit washers are just over the diameter of the indentation. Just seemed odd that the ones on the outside didn't show the marks. But now that I think about it, the orange paint that was on the head (which I removed) must have provided cushion under the fasteners. Obviously the ones under the valve covers weren't painted. Mystery solved?
