M120.980. Joint manifold?
 

I have 6L V12, m120.980.
I'm wondering if I can "connect" the two sides of the intake manifold and put one throttle body, one maf, one map and one iac on it? Or will this disturb the airflow?
I'm thinking about either bringing them both up to the top of the engine or maybe at the back. I am putting it in a boat and space is no issue.
