Will this bore clean up, magnum head content too.

nice thinking out of the box like said…

…But that’s not cleaning up with .010 more bore.

I very doubt it will clean up with .060 (.030 more.

i'm about to try to knock the raised portions off the wall and see how corroded it is. i do see where it looks pitted abought .250" below the deck, i'm guessing it's been leaking a long time and rings always knocked it off lower in the bore.
about to the pull the other head too, crossing fingers they all look good.
