Cometic MLS cylinder head gasket for GM LSX Gen‑4 small block V8 (4.125in bore, right side) features multiple embossed stainless steel layers with Viton outer coatings and a compressed operating thickness of 0.030". The MLS design seals reliably without additional sealants, tolerates mixed head/block materials, resists corrosion and shearing forces, and uses an uncoated center shim layer to adapt to thickness variations and help distribute clamp load evenly.
