Difference between cj/yj headers?

The search function proved useless for my question... Again.
I also found nothing in the FAQs
Is there a difference between a header for a CJ w/258 & standard trans and a header for a YJ w/258 & standard trans?
I prefer to shop locally as much as possible and would rather use my normal local suppliers if at all possible.
Of the 2 suppliers I use most, neither can produce a YJ header for my application, but both can find a header for a similarly equipped CJ.
Will the CJ header work on my wife's YJ, or are they 2 different critters?

I'm sure someone here will have some insight for me.
Thanks in advance!!!

There was a thread about this, I don't remember all of it, but there was a difference between the headers. Here is one for an "87-91". It's not cheap, but I have it on my 4.0 and it made a noticeable difference.

BTW When my YJ had trouble passing smog, the test facility said my Borla header had the 02 sensor reading only 3 cylinders. I called up Borla and they said the new ones fit after the collector and read all 6. They sent a new one out at N/C.

a cj is passenger side front axle, they yj is drivers side so the header is made different to clear.

Also, some cj headers have deeper mounting flange bolt holes. Like over an inch deep.
