The heads are similar so from that aspect, the header flanges should bolt up.

However, the 5.4 has a taller deck height than the 4.6 so where the header pipes actually snake around your engine may lead to some interference, and the collector may not line up with the CATs/Y-Pipe, requiring some new exhaust work. No problem for a typical exhaust shop.

I think at most you might have to make a couple dings in the header pipes if it hangs up on anything, but I think it should be fine, with the collectors lining up a little lower than the stock exhaust hookups.
