There are more issues than just rolling the edge. When the front is cut, it breaks the crossmember loose from the sides and you need to do something to stabilize it or it will move independently from the hood shell when you latch it down. The latches are also a bit problematic as when you redrill and relocate them higher, the surface on the inside isn't flat so the upper half moves from where you want it to be due to it tilting a bit funny when you tighten down the nuts on the studs.
Also along with the cut edge, there is also the loss of support along the edge due to the missing flange. If I were to have one rolled, I would instead have the original flange put back on to stiffen the side back up. Cutting the edge cleanly to have the same reveal is hard. The good news is if the gap is a bit big, just push in on the side of the hood and that will close it up.
