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?

Might seal check those valves/seats while you’re there.
In my experience the valves and seats loose their seal even when the rest of the motor looks really nice.
Didn’t need to test my original heads because when I turned a valve 180 on the seat I could see daylight. :D
