Can I use B or C body manifolds fore better flow on my sleeper GTS?

The problem with a hidden fogger on a big block Mopar (as opposed to a Chevy, or small block mopar) is....
1. You can see it
2. The valley pan is in the way.
On a Chevy or sbm, the manifold seals against the China walls, and the fogger is hidden in the valley. It COULD be done on a maxwedge crossram, since they seal against the China wall too.
From studying the failed effort on my Sixpack, I can't see it being done successfully on any other bbm manifold.
