Cometic Buick Big Block V8 4.400in Bore .040in MLS Cylinder Head Gasket

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.This Part Fits: Year Make Model Submodel 1971-1973 Buick Centurion Base 1973-1974 Buick Century Base 1973-1974 Buick Century Luxus 1968-1974,1976 Buick Electra 225 1968-1974 Buick Electra 225 Custom 1974 Buick Electra 225 Limited 1967,1973 Buick Electra Base 1967,1975 Buick Electra Custom 1975-1976 Buick Electra Limited 1970-1976 Buick Estate Wagon Base 1967 Buick Gran Sport Base 1968-1969 Buick GS 400 Base 1970-1972 Buick GS 455 Base 1970 Buick GS 455 GSX 1967-1975 Buick LeSabre Base 1968-1973,1975-1976 Buick LeSabre Custom 1974 Buick LeSabre Luxus 1973-1974 Buick Regal Base 1967-1976 Buick Riviera Base 1971 Buick Riviera Gran Sport 1975 Buick Riviera GS 1976 Buick Riviera Sport 1976 Buick Riviera SR 1967-1972 Buick Skylark Base 1968-1972 Buick Skylark Custom 1968-1972 Buick Sportwagon Base 1968 Buick Sportwagon Custom 1967-1969 Buick Wildcat Base 1967-1970 Buick Wildcat Custom
