The Cometic MLS exhaust manifold gasket set for GM SB2 Small Block V8 is .066 in thick and constructed from three to five embossed stainless-steel layers. Outer layers are coated with Viton rubber to resist heat up to 250°C (482°F). The center shim layer can be varied to meet thickness needs, while the compressible MLS design seals imperfect surfaces, requires less clamp load, and helps distribute load across the sealing area for durable exhaust sealing.
