Will this bore clean up, magnum head content too.

Looks like the gaskets caused this.

so pretty confident my magnum heads are fine, i was told they were new castings with thicker decks and all that stuff. I have no idea what castings they are though. The intake manifold is a ProComp which you can't even get anymore so this is an old rebuild. Pistons look close to zero deck and I was told the cam is a purpleshaft with maybe .455 lift (but that's the big block cam lift, not the small block) so I gotta measure that too.
I kinda want to get this fixed good enough so it doesn't smoke at all and will last a good while in a powerwagon I use for hauling **** and misc work truck stuff. So pretty much everything in the motor as is would be good to go in the truck.
