Cometic's MLS head gasket for Ford Windsor 289/302/351 engines is sized for a 4.060‑inch bore with a compressed thickness of 0.027 inch, giving a thin multi-layer steel sealing option for tight builds. Embossed stainless outer layers are Viton-coated and paired with an uncoated stainless shim center; no sealants are needed. It resists corrosion and shearing between mixed-metal heads and blocks, conforms load across the sealing area, and helps reduce clamp load and bore distortion.
