If I'm reading this right you need to know how to adapt a BDS manifold to a Max Wedge port?

First, B-1 heads have a different angle and the port size is to big and wide. So if you ask me that is off the table.

Second, The Max Wedge head port is taller so you could cut the top of the runners off and weld on a taller runner to match the Max Wedge port. Seems like a lot of work for what you might get out of it. I would just get the smaller pulley for the blower.
