440 oil pan clearance issues with ARP studs

Hi, Has anyone had clearance problems fitting stock oil pans to B/RB engines using ARP main studs?

I am trying to fit a Hemi pan (bought from 440Source) to a 440 that has ARP main studs fitted. But the back of the pan (the shallow end) is hitting on the rear main studs and nuts. This is my first B/RB engine build so not sure if this is a common problem? The engine was previously running a Milodon deep pan (which fitted) but had ground clearance issue so I am swapping for a 6 Quart Hemi...
