Scratched Cylinder Head = Sealing Problem?

Dont worry, those are nothing to a modern coated Print-o-seal intake gasket. Mirror finish heads are only used in aluminum/iron combos so they slide during different thermal expansion coefficients. The intake is mounted in such a way that it is stable. Check out an edelbrock intakes machined gasket surface, its alot crazier than what you got there. Perhaps its finished like that to control the gasket?
