2G Valve stem seal color?

[smills1840]

I ordered the oem gasket kit from JNZ and received 16 of these valve stem seals. I'd like to drop my head off at the machine shop today, but I'm wondering if I should wait and order a set of the blue viton seals before I do. I can't really tell if these are supposed to be green or grey. Will I have problems down the road with these? They look green in the picture, but more grey in person.

Those are indeed OEM seals.

Blue viton seals are made from a material with greater heat resistance and are obviously worth the buy since their cost is close to OEM anyway. Ultimately the choice is yours, but the oem seals won't fail prematurely just because there are seals on the market that resist heat more.
