Cometic MLS head gasket for Chevrolet Gen‑3 Inline‑6 with a 4.125‑inch bore and 0.030" compressed thickness. Comprised of multiple embossed stainless steel layers with Viton‑coated outer faces, it resists corrosion and seals without additional sealants. The uncoated center shim allows for thickness variation and rebound while the MLS design evens sealing load and lowers required clamp force to help prevent bore distortion.
