i'll try to add some pictures to show this, but my old OEM head gasket is a 3-piece sandwich design.

There is a top and bottom layer of about 0.010 to 0.012" stainless steel, then an inner layer of about 0.004-0.005" stainless held by several crimp joints.

The inner layer is a flimsy little cookie-cutter punched piece shaped to only fit the tops of the 4 cylinder jackets.

i don't have a new one yet to compare but i expect they are slightly thicker in the center sections than at the outer edges due to this inner layer.

Does anyone have details of aftermarket gaskets, please share.

It's been several years now, but the replacement Fel-Pro head gasket was a similar multi layer metal design. It was a bit odd to me as it was nothing like the small block Chevy head gaskets I was familiar with.
