1. A sealing system for an engine, the sealing system comprising:
a single layer gasket, the single layer gasket being formed from a substantially planar flat sheet of material, wherein the substantially planar flat sheet of material comprises an x-y plane; and
a plurality of beads or bead portions profiled on the gasket, where the beads or bead portions are formed with varying heights and widths so as to create portions of varying stiffness, the heights of the beads or bead portions extending in z-axis directions away from the x-y plane, and the widths of the beads or bead portions extending in a direction longitudinal along the x-y plane, wherein the portions of varying stiffness are adjacent to one another, wherein the plurality of beads or bead portions profiled on the gasket include a portion of high stiffness adjacent to a portion of high recovery, the portion of high stiffness having a first bead profile protruding away from the x-y plane at a first angle to a first height away from the x-y plane and extending a first width along the x-y plane, the portion of high recovery having a second bead profile protruding away from the x-y plane at a second angle to a second height away from the x-y plane and extending a second width along the x-y plane, wherein the first angle in relation to the x-y plane is greater than the second angle in relation to the x-y plane, and the first width is less than the second width, and wherein the plurality of beads or bead portions profiled on the gasket includes material that extends in the direction longitudinal along the x-y plane, transitions in a first z-axis direction to a first region below the x-y plane, and then transitions in a second z-axis direction so that the material extends in the second z-axis direction from the first region below the x-y plane directly to a second region above the x-y plane, where the first region and second region are on opposite sides of the x-y plane.
