Chris, you can get it re-nitrided I suppose...but do make sure you have the beargings in your hand before getting the crank ground. I know someone who ended up with a ground crank but no shells for it as when it came to it, the machine shop strangely couldn't get the promised items.
No doubt you are finding that another V6 myth of the indestructible crank is just that...a myth.
