Is the head bolt a problem on the 05 and 06 too? So if you were too do the egr delete, install exhaust to keep the temps down and watch the egts, keep the oil changed, will you be ok or even if you do all that is there a chance you still might have stretched head bolts, blown head gasket or other big issues?
It's not temps that pop gaskets it's cylinder pressures. Truth be known the EGR is the cause of a lot more problems than the heads lifting. I myself wouldn't be worried about the gasket problem so much as the EGR. Just trying to help you make an informed decision. The head bolts in the later years are the exact same as the ones from early years. The difference is at some point Ford/Navistar started using a new method of torquing them from the factory which was supposed to help. I believe it did cut down on a lot of failures but didn't make them go away completely. Personally I think the '05 and up trucks are a lot better as far as driving and comfort than the earlier trucks whether it be a earlier 7.3 or 6.0. Another plus is the 5R110 tranny is hands down a better unit than the 4R100 from the 7.3's.
You mentioned oil and fluid changes too. On a 6.0, IMHO, it is extremely important to do timely oil changes AND fuel filter changes. A lot of other issues people have could have been avoided completely with this kind of regular maintenance. 90% of all injector failures out there would be avoided with this.
