I'm looking at this for my head, it wasn't oiled at the head shop and they handed it to me already with flash rust on it. It's not bad, I can barely feel any texture difference on the gasket surface with my eyes closed.

This should be fine to prep my head with before paint and installation?
Bonus question, I saw a video from a guy who coated the oil galley and timing chain area with Rust-oleum appliance epoxy, to combat oil soak. Thoughts on that and maybe doing the rocker area of the head?
Double bonus, what of chamfering or radiusing the drain holes in the head?
