Fiberglass hood and pin question

If I got pins that were slightly larger than what was there, should I leave the holes in the hood the same size? The new pins fit through the hole, but they are snug.
I can't decide if snug is better so the hood doesn't move around as much, thereby maybe causing cracks. Or if a little bit of movement is better to allow the radiator support to flex without putting stress on the hood.
Opinions?
