Cracked Magnum Heads - Junk or Not?

They can be fixed. But it's up to you if you want to use them again......
Once they drill and pin them they are good as new,i have seen it done
IMO if used in stock form ok re use them but not in a performance setting
your better off spending the money on some EQ's .......................

The ones he's showing there do not need to be repaired. I've pinned and welded more cylinder heads than I can remember. I even developed my own method for repairing blown out Hemi chambers that I torture tested blown on nitro, so I know a thing or two about this. Trust me, those heads he is showing are literally good as new and will go a zillion runs in a 9 second car without ever so much as sneezing. Regular street driver? Those are good forever.
