I'll ignore the debate on crack (pun intended) and skip to the cost benefit analysis:
Since there are visible cracks, why not just have a competent machine shop weld it up, and check flatness while it's in there? Cost should be a few hundred bucks. Compare that with the cost of another head gasket kit if you have to pull the head again, along with 10-20 hours of your time, which isn't free. I know there is a shop in Sacramento that can resurrect cracked aluminum heads, there's gotta be a place in SoCal that will do the same.
And yes, a #14 head can last a long time without issues, if you don't overheat it. I understand the lack of love for the 14 but hey, if you can rebuild it for a few hundred, why not? But bolting it up obviously cracked sounds like a good way to do the same job three times in a row.
