On a backup mail to him I varified that he meant that the 4 end studs does not have anything else except the head gasket to seal it. It may be translation or terminology here. The two locating dowls on the ends stay, the gasket has the holes for this. My motor was overhauled buy PO a few years back and the top gasket I recovered from it is also MLS, nothing around the 4 end studs, but the PO seemed to have reused the old rectangular rubber seal and it was mangled beyond re use.
I have discovered that metric o-rings are designed to have a 15% "squeeze" rate. Thus with a channel of a certain depth and the thickness of the old type gasket as a spacer, there should still be 15% of its diameter that will be squeezed between the two metal surfaces to form a perfect seal. With the new gasket over the channel there may be about 60% that has to be squeezed now as the MLS gasket is solid metal and will not provide extra space.
Basically I cannot confirm this as gospel until someone can confirm that the latest OEM part number 11141-49410 for the headgasket supplied by Suzuki is the same. This also means that most people are fitting NOS aftermarket gaskets at the moment as well.
