factory magnum head replacement options

From everything I've read on this head cracking thing on Magnum engines, the crack happens between the valves & is very minor. I've also been told, if it's not a race engine, don't worry about it, just keep running it if it runs well. That's what I did. The "new" EQ heads from China don't flow anywhere near as good as the originals from Australia either, from what I understand.
