That is the best image I have....Here is a higher res version. Maybe that will indicate. I just looked at the place I originally purchased the GH from and interestingly enough, the image they show is a much darker version! Maybe I got sent an old inventory version?
If you look here on peachparts, the Victor-Reinz gasket is the darker one also:
EDIT: Ah wait hold on that image shows the underside of the gasket....Shoot. Can't tell for sure now.
