If the intake manifold to head uses the same gasket you will probably find companies like nizpro will bolt on a ba/bf intake manifold instead of the fg plastic one so they can fit there current plenum chamber.

And again if the gasket hasnt changed between ba/bf to the FG plenums such as Nitto intakes will be still a direct replacement.

Another problem will possibly be the edits.

As the program will not be up to all the new changes

I have not seen the new falcon yet but if they are still using that crossover manifold they cant have changed that much - ? Its not like they are changing to a v6 twin t. Dont even know why they use that plenum on a non turbo, face the throttle body toward the front of the car - simple. Of course they are still great though. Someone told me that the new engines are very very strong - bigger tolerances.
