Fish give the 6.7 Cummins head gasket failure a break! You know all your examples are from engines that have tuners and are deleted!
This is what the op said in the comments section.
"I believe it was from overheating during a high speed run... wanted to see if the truck was governed. Leaned into the throttle pretty good for an excessive period, got it up around 100mph and shut it down. Not long after that i noticed the bubbles in my coolant overflow. Its a very common problem with the 6.7, too much boost and high EGTs will do it quick. My next mod is a set of pillar gauges to monitor all of that..."
I ran my 11 HO at the limiter for many miles at 104 mph rolling across hyw 10 heading to Phoenix more than once and towed my combined load of 29K+ at 75 or more into strong headwinds many times with no ill effects!
Add a tuner and do the deletes it's a different game.
