The Cometic MLS head gasket pack is a multi-layer steel replacement set made for 4.00 in bore applications, offered here as a .040 in thickness 3-pack suited to H‑D Twin Cam setups. MLS construction uses embossed AMP-coated outer layers and an uncoated stainless shim to meet harsh sealing demands. That layered design reduces required clamp load, minimizes bore distortion and helps distribute sealing load across the combustion area.
