Change in head gasket?

I just received a nos head gasket for my 850. It is different from the one I took off. The opening for the cam chain tunnel is smaller, so it covers the groove that the rectangle o-ring sits in. Did I get a wrong gasket, or should I use it without the o-ring?

Is the new gasket MLS (multi layer steel)? That's the newest type. They don't use the rectangular O-ring nor loose seals around the outer cylinder studs.

I believe it is MLS. Here are some pics:

That gasket is not MLS. Regardless though, it's clear that the rectangular O-ring is not to be used.

EDIT: I think that gasket is an older version. The one in the photo is the current MLS type.

Thanks. Should the rectangle groove be filled with anything?

no need to fill with anything, same with the MLS gasket.
