Default 850 intake N/A manifold swap valve?
I have the manifold off my 97 850R to do the PCV and figure I might as well do the NA manifold and TB swap. Im told there is a specific manifold to use as some have a "flap" or something. I even tried Car-Part.com--Used Auto Parts Market and when you search for the manifolds it gives 3 choices
1 4 valve with egr
2 4 valve witout egr
3 2 valve

is there a specific year that will have exactly what I want or which one of the above do I need?

thank you ahead of time

Yeah, what rspi said; think you're confusing VVIS and EGR; not even close to being the same thing.
