I don't think it's so much that they're wrapped up in 6.0 issues but more that they want to be safe. They want to know that they can make big power without thinking twice if their HG's will blow. It's not only 6.4 guys that do it too, if you go on the Cummins forums, there are a similar amount of guys with studs as on here. Same with a Duramax forum. The main reason many 6.0 trucks have HG problems even with studs is that there are simply not enough fasteners holding the heads on the motor. Combine the troublesome oil and EGR cooler and 4 Head bolts and its clear why many 6.0's have blown gaskets. However, if you maintain both a 6.0 and 6.4 they should treat you just fine without studs.
