I got my BlackStone report on the crew cab. The 6.9 is all original with 321,000 miles. It shows only high potassium and sodium which indicates coolant getting into the oil. As I feared, it is likely a headgasket. But at that kind of mileage, it's not really a surprise.
I've won a "different" engine off of ebay today. I may end up putting the 7.3 in my black truck in the crew cab and "different" engine in my black single cab.
