Service mechanics for fleets have stated the 5.4 can easily reach 350 to 400 k miles before requiring a full tear down. That said, one should expect to service timing components and oil pump, inspect the cams and liters for wear, every 90k to 100k miles. Further, one should inspect plugs on a shortened interval of 30k miles

I just changed all that in mine, including DPFE - and it appears to have created all kinds of issues as well. Truck races at startup, then virtually stalls, then hunts...none of which occurred befote, which I just chalked up to my incompetence by missing a vacuum hose or something, but all hoses are correct and I didn't have this after changing the intake at just over 186785 miles....
