Intake manifold and oil pump gears

Hi, I want to use a Malossi intake manifold (22158000) on a PX Lusso for a carb upgrade.


My question is: how to remove the drive gear for the oil pump. Do I need to split the cases, or can I just pull it out. Maybe another option is the use another manifold that doesn't cover the oil pump hole and leave the gear there.

What should I do. If possible I would like to avoid having to split the cases.
