The few I got around 150-170k still had hash marks, but the cam bearings were flaking.
If all your cam bearings look good, it's possible 50k.
What year block, does it have oil port to cylinder heads?
Get a magnifying glass and look between the valves for cracks or are you going with other heads?

I believe it’s a 1994 5.9, going with the stock heads, probably port them a bit and clean the valves, the actual valves have no real build up. I’ll try to snag a picture inside the ports. Although what ever my machinist recommends, I’m no expert but the valves don’t look sunken. Ultimately with the valves out I can see if there’s any crack, as of know I don’t see any.
