A static cylinder head gasket assembly includes an inner distance layer having an opening extending between opposite planar sides with the opening being configured to register with a cylinder bore of an internal combustion engine. A plurality of inner functional layers overlie each of the opposite sides of the inner distance layer. The inner functional layers have axially aligned, nested annular sealing beads extending about the opening in the distance layer. The gasket assembly further includes a plurality of outer functional layers separate from the inner functional layers. The outer functional layers have annular inner peripheries spaced axially from one another to provide a gap configured to receive at least a portion of the inner distance layer therein. The outer periphery of the inner distance layer is captured axially between the outer functional layers and thus, the inner distance layer is prevented from being disassembled from the outer functional layers.

1. A static cylinder head gasket assembly, comprising: an inner distance layer having an opening extending between planar opposite sides, said opening being configured to register with a cylinder bore; and inner functional layers on said opposite sides of said distance layer, each of said inner functional layers having a plurality of abutting metal layers, each of said abutting metal layers being formed of resilient, springy metal and each of said abutting metal layers of said inner functional layers having axially aligned, annular sealing beads received in one another in nested relation, wherein said annular sealing beads extend about said opening in said distance layer, a plurality of metal outer functional layers separate from said inner functional layers, said outer functional layers having annular inner peripheries spaced axially from one another by an annular gap, said annular gap receiving at least a portion of the inner distance layer therein, said inner distance layer has an annular outer periphery and further including an outer distance layer sandwiched between said outer functional layers, said outer distance layer having an inner periphery configured in radially spaced relation from said outer periphery of said inner distance layer. 2. The static cylinder head gasket assembly of claim 1 wherein said at least a portion of said inner distance layer floats axially between said outer functional layers in said gap and radially relative to said outer distance layer. 3. The static cylinder head gasket assembly of claim 1 wherein said inner distance layer and said outer distance layer have different thicknesses. 4. The static cylinder head gasket assembly of claim 1 wherein said axially aligned, nested annular sealing beads are full beads, said full beads on one side of said inner distance layer and said full beads on the opposite said of said inner distance layer facing axially toward one another in mirrored relation. 5. The static cylinder head gasket assembly of claim 1 wherein said axially aligned, nested annular sealing beads are full beads, said full beads on one side of said inner distance layer and said full beads on the opposite said of said inner distance layer facing axially away from one another in mirrored relation. 6. The static cylinder head gasket assembly of claim 1 wherein said axially aligned, nested annular sealing beads are full beads, said full bead on one side of said inner distance layer and said full beads on the opposite said of said inner distance layer facing axially in the same direction. 7. The static cylinder head gasket assembly of claim 1 wherein said plurality of inner functional layers overlying each of said opposite sides of said distance layer includes a different number of inner functional layers overlying one of said opposite sides than the number of functional layers overlying the other of said opposite sides. 8. The static cylinder head gasket assembly of claim 1 wherein at least some of the individual functional layers have different thicknesses relative to one another.
