That's electrolysis.  They can be saved.  How deep are the pits?

I have used a good citrus hot tank,  glass bead, fill imperfections with Belzona 1111 and machine flat.

Looks to me like the wrong gaskets were used.

Easy fix... Grind out ALL the rot and then tig weld up... Then surface flat and you're back in business good as new. I do this all the time on customer's heads... And beyond... It's just a matter of having the right tools and knowing what you're doing...

Good example:
Pair of Ford heads I did for a guy on here... So rotten that they leaked on the outsides. Now... Flat and sealed up bitchen.

Just depends on how much rot and welding needed... Typically the grind/weld repair parts runs between 50-100 (minor to major) and cc & surface runs 95 bucks... I cc all pairs of heads that I surface just because I want to make sure they come out exactly the same.
