Will this bore clean up, magnum head content too.

Maybe you'll get lucky. I could see one sleeve. But two or more and I'd be huntin a block. Good luck with it man.

gonna pull the other head tonight, crossing fingers the other bank has good bores still.
called machine shop, they can sleeve it. he said that made more sense if only one bore is bad. my brother has a few 360 cores and also a set of RHS indy-X heads. I'm not one to scrap stuff over something that's perfectly fixable, so hopefully i'm just looking at a sleeve and I take a shot at a proper cleaning/reassembly.
I wouldn't mind scrapping the magnum heads and trying to get those Indy-X heads though.

Honestly I was thinking I was looking at a new set of heads. So one sleeve and new rings and some gaskets isn't too bad. I had always planned on getting into this motor some to see what was in it and calc the compression accurately. The previous owner couldn't remember what cam was in it. I think I need to order a degree wheel.
