as long as you connect the inlet line to the outlet line so it can make the loop, it will be okay. What will probably happen is the hotter oil will drop in pressure, particularly at idle by 2-3#.
An alternative is to simply remove the oil cooler adapter and then you won't have to loop the lines together. If you are running a biggie oil filter adapter, this will put you back to using a stock type oil filter, tho.
