OP, you just did your 6.0h no a favor, IMO, and in 5k you may even want to do it again.
Lets hope so! lol I love the truck but when the wife and kids take it on long trips like this hauling a lot of weight I still get nervous! She's been good to me and never a let down with 135k on it. But you know the reputation
I know it well.
Mine had studs, FelPro MLS gaskets, a reman FICM with the Atlas flash, BulletProof Diesel water pump, ELC coolant, and DIY bypass filter. I ran a lot of Valvoline 10w30, and a couple fills of the Delo 15w30. I found LubeGard BioTech better than the popular Rev-X and Archoil, and either of those was better than HotShots for stiction and injector care.
If you leave them stock, and take care of them they can last. Problem is the lack of head bolts around each cylinder, and most tuners increase cylinder pressure over what the TTY head bolts can handle. If you took yours to Ford for updated flashes over it's life, they began to suck power back out with later flashes to try and save the beast. The Atlas flash puts all the good Mojo back in, and really makes the truck fun to drive without hosing reliability.
Yes, I love the Atlas 40 FICM tune, really woke the truck up. Combined with the 4" straight exhaust, its a great running truck. Just a quick update, they made it first to Savannah GA to the Mother-in-laws which was a 4.5 hour trip fully loaded and then they drove another 3 hours the following day to Perry GA to the Horse show. All without a single hiccup and averaged 13mpg loaded!
