No, I've pulled heads on a 6.0 in the truck, most ppl pull the engine out to do any major work like heads, it's suppose to be easier I guess. You can do a lot of engine work "engine in truck" on the 6.0, no real need to remove the cab. The 6.0 looks bad, but once you get the crap tore off on top the engine is like a foot down and looks so tiny, especially with it's giant heads off.
