"Couldn't you use headers for a F-150 4x4 302?"
Good luck finding some.
Ford didn't put the 302 in a 78-79 bronco or a 70s 4X4, i don't even think they put them in 4X2 F250s and 4X2 F350s either. I have never even heard of a F250 or F350 with a 302 VIN code.
The 351W has a 1.3" taller deck and that could cause clearance issues with "F150 4X4 302 headers".
Incase you're wondering why ford didn't put the 302 in 4x4 in the 70s. It is because ford had motors that would do the job better like the 300I6, 360, 390, 351M, and 400.
In the 80s and 90s ford only built four engines 300I6, 302, 351W, and 460 so they didn't have much choice.
