Cometic's MLS head gasket for Ford Windsor 289/302/351 engines features a 4.030‑inch bore and a compressed thickness of 0.056 inch, providing a durable multi-layer steel seal for high-output engines. Embossed stainless outer layers are coated with Viton and paired with an uncoated stainless shim center; no sealants are required. The design resists corrosion and shearing between aluminum and cast-iron surfaces while reducing clamp load and bore distortion.
