The OE style pickup has a "shoe" that touches and establishes clearance for flow into the screen. Some aftermarket have the "shoe" and some don't.

If you have the shoe type it is supposed to touch. I certainly believe it has worked fine for many with the clearance. Still I have heard cases where vibration broke the pickup. Not pretty. Stories were on MOPARTs so they must be true... right? Personally, I would re-do it or have the shop re-do it. Plus you get every last bit of pan capacity.
