Ben,

I believe the 996 intake runner port size and the 986 are the same. They are the same head to the best of my knowledge.

At a high level, you would need to: laser scan the 996 aluminium intake runner left and right bank parts; develop the 3D model; adjust the height if possible (not sure this would be easy to adjust without negatively impacting geometry); map the 986 head holes onto the bottom flange of the model; incorporate fastener feature up top as needed; 3D print in suitable material.

I am not sure about fuel rail and injector fitment

Please make this. I have been wanting adapters for years!
