I've always preferred the hood without holes so I align the hood perfectly then open the hood and install the pins on the core support while applying a dab of paint on top of them. I gently close the hood until they touch the pins and then open the hood where I can see the paint and exactly where to drill for the pins with a small pilot hole and then finish it off with a larger hole and install the rest of the hardware. For me this guarantees each hood and pin alignment is perfect.
