The factory manual says to be sure to install the new head gasket with the "TOP" side up..... fine, except the replacement gasket is not marked.

The only difference I see from side to side of the new gasket is that the metal "rim" that circles the cylinder holes has a larger lip on one side and a bit narrower lip on the other side. Everything else looks the same on both sides.

Narrow side down? Up?

I assume it must matter or they wouldn't make the two sides different.
