JD, you seem a lot more knowledgeable on the IH diesels than I am, but I'll tell you what I was told from 2 different mechanics, and the parts counter man at our local NAPA (used to be with our local IH/Navistar dealer as a parts man):
I was told that the 6.9's were NOTORIOUS for breaking/cracking heads. When I was looking for a replacement engine for my 86, every one I seemed to run across also had broken heads. I was also told that this was corrected in the 7.3 IDI's. I have never personally pulled a head off of either, so don't know there is a difference or not.
In any event, I am way more satisfied with my 7.3 repower than I was with the 6.9 I pulled, but the 6.9 was beyond tired. (used a gallon of oil every +/-500 miles, depending on how I drove it) The 7.3 uses some oil (gallon every 1500 to 2k.. which is still a lot for my liking) but sure don't smoke like the 6.9
The only thing I don't like about my 7.3 is for some reason it is harder starting than my 6.9 was.. But could need new glow plugs.. I checked them about a year ago when I did the engine swap, and I always checked my 6.9 as the season started to change colder.. The few minutes to check was far better than counting on it to start and being left stranded.
I can agree about the thicker cylinder walls of the 6.9 being better though..

Many owners of tractors travel long distances to attend these shows and they usually take their restored iron along with them. Safe trailering practices and inspections will ensure that the event is a fun one. A good habit to develop when using a trailer is to give that �quick look over� before taking it on a trip. Before hooking up to it check the tongue for proper operation. The latche
