Cracked Magnum Heads - Junk or Not?

Keep in mind, moper speaks from real world experience. Those magazine articles are jaded into making sure their sponsors look good. I take anything in magazines with a grain of sand anymore. moper doesn't have to blow up the skirt of any sponsors. Keep that in mind.

I wrote for the magazines...hell, I started some of them! And you're right...it's all bullshit. That's why I stay away from them anymore.
As for those heads, I would bolt those on without even thinking about it. I've run stuff like that in everything from grocery getters to Top Fuelers. Not all cracks are created equal. It takes experience to know what you can get away with and what is scrap. The pics the OP posted show heads that are good to go for nearly any application.
