Cometic MLS exhaust gaskets for GM Gen-3/4 small block V8s (.030") use multi-layer steel construction with embossed outer layers and an uncoated stainless shim center. Built to withstand extreme cylinder pressures, they maintain torque, resist corrosion, and conform across varied head and manifold materials. These round-port gaskets require no sealants and resist burn-through or push-out.
