Cometic MLS head gasket for Buick Stage I/Stage II V6 (3.860 in bore) in .070 in thickness. Multiple embossed stainless steel layers with Viton-coated outer surfaces and an uncoated shim create a reliable, sealant-free seal for higher-output engines. The multi-layer design suits aluminum-to-aluminum and aluminum-to-cast-iron head combinations, resisting shear and corrosion while distributing clamp load to reduce bore distortion and improve sealing longevity.
