Default Valve seals

I've bought thin wall viton valve seals, but I'm not sure if I
should use them or not. This seals have sealing material
only on the top (see pic1) and part that seats on valve
guide is only metal.

So, I'm worried if this seals will be good, or do you think that I
should use standard seals (pic2)

The oil is not going to run up hill....so I think you be fine there....why not pop one on and see how snug they are at the bottom around the guide posts.

I'd use the "blue" ones

I think the purpose of the seal is to wipe the valve stem of excess oil so should be good.

Those are actually the best kind of PC seals you can get.
I'd run them.
