High Volume oil pump clearance issues?

So Jake just picked up a 2001 Dakota with the 3.9 v6 in it for $500 that he's going to beat the dog crap out of for the next 5 years while attending the University of Maryland. Oil pressure fades as the engine gets warm. We're gonna drop the pan and put a pump in it, and want to upgrade to a high volume pump. I figure with the 150k on the clock, more volume can't hurt. The listing for a high volume pump says to check pan/crank clearance. With all the Dakotas being driven on here, I figure someone can answer this - Has any of you had clearance issues?
