I have been told that most of the cylinder gasket failures of the 6.0 can be attributed to the "rocker box" in the cylinder heads. The rocker box is basically a large aluminum washer that makes contact with the block, allowing the cylinder gasket to "work" between the head and block, causing the gasket to fail. I understand later 2007 6.0's came with a "commonization" head, basically the 6.4's head that did away with the aluminum rocker box. Thus the reason no 6.4s have had gasket issues even when modded to output levels of 500+hp. Curious if anyone owning a 6.0 have looked into swapping out troublesome 6.0 heads for 6.4 heads and do they fit the 6.0 block.
