Cracked Magnum Heads - Junk or Not?

First - to clarify - I have submitted to a magazine before. For all I know it got tossed within seconds because they sure never called me but there's not much call for rearview mirror repair articals...lol. Also - I can and do blow up skirts - but not a car magazine's :D
The EQs are shipped bare. The shop where I saw them (they do my machining now) has used many sets on class circle track engines over the years and they work like mad - when matched with the right components. The better flow numbers come from a much better casting quality, a good valve job, and performance valves. There is no "out of the box" flow ratings because they don't come assembled - just like the RHS heads - and if you think a top notch performance valve job isn't worth an additional 5% flow and better cylinder sealing you are paying the wrong people to do it.

"I'm not sure what you mean by that last sentence. Could you explain?"
These heads are iron, and limited by minimum cross section due to the pushrod pinch. They flow well - very well - for what they are. But as soon as you have to start whittling to get more air though them, the costs go up because iron takes twice as long or more to port than aluminum, you can't just hog them out and get huge numbers, and ultimately the iron heads are heavier than the aluminums. So once you have to spend more cash, the aluminums - IMO and using my local pricing anyway - are more overall cost-effective.
