I have a 02 SD F-250 with a 5.4
It's been a good motor so far
I had a 99 with a 5.4 as well, and the guy that I sold it to drove it past 150,000 before trading it in trouble free
The spark plug issue showed up in the 00 and later trucks
In 99 there was a issue with the heads gaskets on some trucks
It was the pass side more the the drivers side
So check to see it leaking (look for oil leaking between the head and block)
But as other have said they get allot of miles out that motor
I've known 4 people that have broke 300,000 all trouble free
