Need to make a decision fast 5.7/6.1/340

Will those manifolds fit facing forward by swapping sides? Just wondering for a Single or Twin Turbo install.

I have spare LX manifolds. If you want to try those, I will send them to you; just pay shipping. I would think the jeep ones are too long. If you are mounting them upside down, a set of shorty truck headers may be ideal, but I don't actually know.
