x2 what Pic_jon said... I'm my research on the 6.0L, it doesn't do well with blown head gaskets and overheating, in that the heads easily warp or crack. A preemptive repair tends to hold up well and prevent damage down the road. I was in a similar situation with my RV project in deciding what to do.
We replaced the EGR in mine before I drove it back to NC (from tx) and after the repair it blew tons of water out the tail pipe as well as steamed a good while.
Note: There were tons of other improved/updated parts that should be installed if your that far in. Almost all the orings in the stand pipes and high pres. oil system have been revised or improved. They help with the hard starting etc.. Turbo drain tube and other seals/gasket updates..
Good luck..
