will any other b series oil pans work?
or will they have a deeper pan making it hit the ground?

 

All Bseries pan are interchangeable.

 

Wrong. All B series pans are not interchangeable. The LS, B16, and CRV are all the same. The GSR/ITR pan is deeper and bolts up differently to allow the block girdle and the different windage tray and pickup to clear. The GSR or ITR pan requires modification.

 

correct

 

So B16 with an added block girdle requires a GSR/ITR/Moroso pan?

 

Yes, a B16, LS, or B20 with a block girdle will require a GSR, ITR, or moroso pan, with the GSR/ITR pickup and windage tray.
