Cometic's MLS cylinder head gasket for Ford Windsor V8 289/302/351 engines is specified with a 4.100" bore and 0.089" compressed thickness to seal high-output setups without sealants. The gasket combines embossed stainless outer layers coated with Viton for heat and corrosion resistance and an uncoated stainless center shim for thickness control. It works with aluminum heads on aluminum or cast-iron blocks and helps distribute clamp load evenly to minimize distortion.
