Have a dum question about headers. How close are the heads on a 2.9 and a 4.0. Will a pair of headers off a 2.9 fit on a 4.0. Are the exhaust ports the same. thanks :icon_confused:
 
I believe they are the same but the y-pipe is different.
 
I haven't tried it personally, but I have been told that 2.9 and 4.0 headers are interchangeable. The part number for the gaskets is different though.

The Y-pipe is different because the 2.9 only ever used one oxygen sensor, the 4.0 always had at least two.
