Scratched Cylinder Head = Sealing Problem?

Thanks for the good advice; I'm learning a lot from these forums. Sounds like I was really overthinking the scratches. This is the first time I've installed an intake, so I'm trying hard to get it right.

The engine had the original 2 barrel on it until a couple months ago, and I can see the guy who owned it before me didn't bother to clean up very well when swapping the manifold/carb. He also didn't change over any of the kickdown linkage or use any sealant on the bolts. What a mess. Hell, he didn't even bother to wash the 50+ years of dirt off the intake bolts before reusing them. Turns out he was a Chevy guy only owned the car for a couple months. Nothing against Chevys, just venting a little bit.
