Bryan, Callie's utilizes two different types of hardening processes on their Dragonslayer, Magnum, and Stealth crankshafts. Perma-tough, and Dura-tough.
The tricky part is figuring out which process was used on your crank, because apparently some Dragonslayer cranks brought into America (the Dragonslayer is made in Asia) receive a Perma-tough process, and some receive a Dura-tough process. The Perma-tough process is most desirable, because it allows the crank to be turned out to roughly .060, and won't need re-hardened.
The Dura-tough process, not so much. .010 is getting into the outer edge of the good stuff, and once you get out to .020, well it will need to be re-hardened.
I find conflicting info concerning what cranks get which process, and I don't know how you'd figure that part out. The re-hardening process will be costly, because it typically means re-truing the entire crank, due to the heat causing it to be distorted.
If your in a hurry, you might want to simply buy a new one, and sell the one you have. Great news on the block, by the way! As Greg Weld says, and I quote, "Ain't hot ridding fun!"
