Picked up a 5.2 magnum for Free

Well, further inspection and the notorious head cracks are evident. There is no sign of coolant burning, leak down test was good, so now I'm unsure what I should do. Probably shouldn't have even looked, but at the minimum I wanted to reseal it. The bottom end is so nice. The timing chain doesn't have a bit of slack in it.

I have read, where people have run the heads with no problems. Anyone done so?
