Cometic MLS head gasket for Chevrolet Gen‑3 Inline‑6 with a 4.125‑inch bore and 0.036" compressed operating thickness. The layered stainless construction uses embossed, Viton‑coated outer layers for heat‑resistant sealing and an uncoated stainless shim center for adjustable thickness and rebound. It seals high‑output engines without sealants, distributes load across the sealing area, and helps reduce clamp‑related bore distortion.
