im doing a 5.4 2v conversion and wondering if anyone knows what headers will work and what x or h pipe, will the factory 4.6 exhaust work?

the 4.6 headers will fit the heads just fine but the block is taller so a remedy for the x or h pipe will be needed. or you could spend 1200 on long tubes made for this swap but damb thats a hell of alot of money when you could run shorty's and lengthen the mid pipe

as long as the headers fit ill modify a pipe for it, thanks for the help

The heads will physically bolt to the heads (same heads as 4.6) but there needs to be some pretty heavy modification of the headers if you use long tubes.

All that is need for the mid-pipe is to widen it.
