I replaced mine because they had lost the "cup", flattened out. I'd read cupped side down and couldn't tell on the old ones.

I was un-aware they were cupped to start with! as you can imagine, I have quite a few laying around and none exhibit any cup-ish-ness. Can't imagine why they would want them to be cupped, I would think that would consume a good part of the torque you're putting on the bolts or some such. I'm confused. again....

Attached photo of my new ones from Nissan

Finally picked up the parts from the dealer.

Thanks for that. I work on a lot of stuff, make mistakes sometimes. 

At least I could provide the correct part numbers.

I am sorry to correct you but you are actually correct.  The original head bolt washers have a smooth edge on the top side and a sharp edge on the bottom side.

 

Got your back! :)
