Cometic MLS head gasket for GM LSX Gen‑4 small block V8 with a 4.125" bore and nominal .080 in thickness, left-hand side. It delivers robust sealing for high-output engines without additional sealants and fits aluminum heads against aluminum or cast-iron blocks. Multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated shim layer offer corrosion resistance, improve load distribution and require less clamp load to reduce bore distortion.
