Will this bore clean up, magnum head content too.

almost all is outty corrosion. I scraped it with a soft metal that was cut clean. Then more scotchbrite. Looks better but still really bad. The worst part is up at the top. You can see the bad corrosion.

I'll get some hate, but I'd run it. It'll kinda clean itself up to a point.
