Cone Shaped Front Wheel Bearing Retaining Washers

[Oldgearz]

Just ordered two front wheel bearing retaining washers which are slightly undersized so I can put on dust caps. Don't know why Henry forgot those. Anyway, the new washers are slightly conical in shape, and I don't know if this is by design or by cheap manufacturing. I have never seen this before. Should I crush them flat or install as-is? If I install as-is, which way do they go, raised center hole facing in or out?
