copper header gaskets..which side????

im in the middle of my header swap so far not so bad,

im to the point in installing the headers and the copper gaskets(summit copper gaskets) one side has a raised ridge areong the port hole and the other side is flat...im assuming the ridge fits inside the port hole and the flat side faces the header??? please need some feedback as i dont want to install wrong...thanks!!!

Isn't it great when they incorporate something like this and then don't offer guidance? My copper gaskets are flat on both sides and so I never had this issue. However, I see gaskets like this frequently in the things I work on daily. In your case, here would be my choice and why. Your heads have the largest surface and are much less subject to change. Put the raised side towards the header's flange.

I installed mine with raised to header flange......but only after I matched it to ensure a good spread. It made sense at the time.....and when someone like KC confirms that thinking......I'll stay with that idea.

My guess is that because Summit sells a few different header designs (D port vs. Round) for C4's their safe bet is sealing to the consistent head surface (as KC mentions) instead of taking a chance?
