unfortunately i don't have much knowledge on the 2.6 IM. but as you stated, i would just secure the switchover valve in one position and leave it alone.
i would be very surprised if the 2.6 did not have some sort of ISV (but i've seen stranger things on these cars) it also looks like the 2.8 didnt have any sort of EGR system attached to it))
do some reasearch, i know its been done, but i didn't look in to it too much as we don't have to deal with those IM manifolds that you guys have

and Fortunately I do!

They get breaks in the seals on the top/bottom where it's plastic, as far as I know there's no replacement for the gaskets so you'll have to make a gasket for it if that's the case. That or obtain another intake manifold.

Do note there are at least three different versions, two for the revision 1 engine 1991-1993 (even early 94 cars sometimes have these such as mine) and the revision 2 engine 1993-Onwards. The main way to tell is on the front left side of the front. (or the part number if the sticker is on)



If you can see that is a 93 intake manifold, the main difference being that the idle control valve hole on the rear is smaller on the first generation, which has a different ICV.



Second Gen (1994 - On)




First gen (1991-1993)




Now I've mentioned three types and only listed two?

I replaced my 93 intake manifold with what appears to be a 91 intake manifold and it has a bit of metal or something on the side that appears to do nothing? Anyway I can confirm that it fits in a '93 engine as it's sitting in mine now.

P.S Pro tip when you are re-inserting the injectors, put some vaseline on the seals and they'll slip right in! Put them in the fuel rail first and then the fuel rail in the manifold, using the screws/metal bar to clamp them down.
