Are you refering to the line at the outer row of bolt holes?
I'm sure you know this but the triangle area around each of the outer bolt holes are where the cutter/head deflect, a combination of the setup, machine spindle,interupted cut, and casting not being rigid as one might like. Obviuously not intended to be used as the final surface prep to seal a head gasket, but a production style finish.
Also, the coolant ratio looks weak and the cutter inserts need to be rotated.
I combined the pictures and rotated them. You're the expert but to me the marks look qualitatively different.
