Rather than have a hole in the plate to allow for the pick up tube, I would drill a hole in the exact size of the pick up tube, and a set to account for the mounting screws, and let the plate perform that function.

If the bell is large enough it needs trimmed to avoid touching the pan. The bigger bell eliminates the need for a anti-vortex plate. The top of the big bug screen does this in American V-8s. Lynn E.
