I'm pleasantly surprised that the Ford 6.0 did so well. I've been told that it's one of the strongest Ford blocks once all the quirks are worked out. So far I've been very pleased with my bulletproofed 6.0.
While the 6.0L did have some issues, some of these issues in the aftermarket world should have been attributed to bad tuning rather than the 6.0L itself. Being one of the first Powerstoke engines that could be tuned electronically, novice tuners would crank up the timing and fuel delivery at lower rpms causing very high cylinder pressures. This would cause head bolts to stretch and gaskets to blow. The same thing happened when the Cummins 6.7L first came out blowing head gaskets left and right.
As tuning software became more sophisticated and tuners became more knowledgeable, these problems became a thing of the past. However, many on the internet don't know this and still contribute these old issues to anything tuned even though they don't even relate. Heck, even the software mapping the OE's used back then has advanced giving them better and more smoother fuel mapping. The fuel mapping on the old ECM's used for the 6.7L Cummins when it first came out are much different with less parameters available than the ECM's used on the current engines. More parameters means smoother fuel mapping and greater ability to control low rpm cylinder pressures.
