Had a 5.4 in my 98 Expedition. Replaced the head exhaust gaskets, both sides, TWICE. They liked to leak. Cast iron header to aluminum head. Once started leaking it would etch into the aluminum. It only had 60000 miles on it when we sold it after 16 years.
Having the 5.4 as a base model engine in a Superduty is/was the same as getting the V6 in the F150.
