Little bit of a rant about Mopar heads...

Well, I also forgot a more thread-relevant question, Has anyone had cracked heads welded up? I don't get why you can't grind the crack out, take some Ni 99's, preheat, weld, postheat, (Like you're supposed to welding cast iron) And have the seats redone. It may crack again someday, but if it's cast iron, it'll crack eventually no matter what you do.
