I think I know the holes you mention. I thought they were needed to somewhat regulate/relieve some pressure in the lowers when dampening since that's just for lube area. I also searched a while ago on this topic as I was trying to figure out if the holes were supposed to face forward, backwards or sideways, but never came across anyone talking about those holes. I put mine sort facing to the sides - not sure if they are needed, so can't help you there.
