Cometic’s MLS head gasket for 1975–1987 Buick V6 Stage I & II (196/231/252) features a 3.860" bore and .040" compressed thickness. The multi‑layer stainless steel construction with Viton‑coated outer layers is intended to deliver dependable sealing without sealants, resist shear between head and block materials, and distribute clamp load across the sealing area to reduce bore distortion in older Buick V6 rebuilds or high‑stress applications.
