The Cometic MLS head gasket for Buick Big Block V8 (4.400" bore, .040" compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces for heat-resistant sealing. MLS construction rebounds to resist corrosion and withstands shearing between dissimilar metals, making it suitable for aluminum-to-aluminum or aluminum-to-iron applications. It requires no sealants and improves load distribution with less clamp load and reduced bore distortion.
