The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.100in bore) with a compressed operating thickness of 0.036in is a layered stainless steel gasket for high-output builds. Embossed outer layers coated with Viton resist heat and sealing challenges while the uncoated center shim enables thickness tuning. MLS construction is specified for aluminum-to-aluminum and aluminum-to-cast-iron pairings and seals reliably without added sealants, distributing clamp load evenly.
