# Cometic AMC 390/401 Gen-3 V8 .030in MLS Cylinder Head Gasket - 4.250in Bore Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.030". 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. - The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes - The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements - Requires less clamp load creating less bore distortion - Conforms load distribution across the sealing area - Embossed Outer Layers Coated w/Viton This Part Fits: Year Make Model Submodel 1962 American Motors Ambassador 400 1963,1967 American Motors Ambassador 880 1963,1966-1967 American Motors Ambassador 990 1968-1970 American Motors Ambassador Base 1971-1974 American Motors Ambassador Brougham 1958-1962 American Motors Ambassador Custom 1961 American Motors Ambassador Custom 400 1959 American Motors Ambassador Deluxe 1968-1971 American Motors Ambassador DPL 1968-1972 American Motors Ambassador SST 1958-1961 American Motors Ambassador Super 1966-1968 American Motors American 220 1968 American Motors American 440 1968 American Motors American Rogue 1968-1970,1978-1979 American Motors AMX Base 1966 American Motors Classic 550 1966 American Motors Classic 770 1978-1979 American Motors Concord Base 1979 American Motors Concord DL 1979 American Motors Concord Limited 1972-1975 American Motors Gremlin Base 1976 American Motors Gremlin Custom 1977 American Motors Hornet AMX 1970-1971,1973-1977 American Motors Hornet Base 1971 American Motors Hornet SC/360 1971-1977 American Motors Hornet Sportabout 1970-1972 American Motors Hornet SST 1971-1974 American Motors Javelin AMX 1968-1974 American Motors Javelin Base 1968-1972 American Motors Javelin SST 1970 American Motors Javelin SST Mark Donohue 1970 American Motors Javelin SST Trans Am 1967 American Motors Marlin Base 1971-1978 American Motors Matador Base 1974 American Motors Matador Brougham 1974 American Motors Matador X 1978 American Motors Pacer Base 1979 American Motors Pacer DL 1979 American Motors Pacer Limited 1969 American Motors Rambler 440 1969 American Motors Rambler Base 1969 American Motors Rambler Hurst SC/Rambler 1969 American Motors Rambler Rogue 1967-1968 American Motors Rebel 550 1967-1968 American Motors Rebel 770 1969-1970 American Motors Rebel Base 1967-1970 American Motors Rebel SST 1970 American Motors Rebel The Machine 1966 American Motors Rogue Base 1979 American Motors Spirit Base 1974 Bricklin SV-1 Base 1974-1983 Jeep Cherokee Base 1981-1982 Jeep Cherokee Chief 1983 Jeep Cherokee Pioneer 1974-1978 Jeep Cherokee S 1978-1980 Jeep Cherokee Wide Track 1975-1978,1983 Jeep Cherokee Wide Track Chief 1971-1981 Jeep CJ5 Base 1977-1980 Jeep CJ5 Golden Eagle 1980-1981 Jeep CJ5 Laredo 1975-1981 Jeep CJ5 Renegade 1971-1975 Jeep CJ6 Base 1976-1981 Jeep CJ7 Base 1977-1979 Jeep CJ7 Golden Eagle 1980 Jeep CJ7 Golden Hawk 1980-1981 Jeep CJ7 Laredo 1976-1981 Jeep CJ7 Renegade 1972-1973 Jeep Commando Base 1984-1991 Jeep Grand Wagoneer Base 1984-1985 Jeep Grand Wagoneer Limited 1971-1973 Jeep J-100 Base 1970-1973 Jeep J-2500 Base 1970-1973 Jeep J-2600 Base 1970-1971 Jeep J-3800 Base 1971-1973 Jeep J-4500 Base 1971-1973 Jeep J-4600 Base 1971-1973 Jeep J-4700 Base 1971-1973 Jeep J-4800 Base 1974-1988 Jeep J10 Base 1974-1988 Jeep J20 Base 1972-1982 Jeep Wagoneer Base 1982-1983 Jeep Wagoneer Brougham 1973-1976 Jeep Wagoneer Custom 1979-1983 Jeep Wagoneer Limited ## Details - **Price:** 155.95 CAD - **Vendor:** Cometic Gasket - **Type:** Head Gaskets ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 155.95 CAD | In stock | ## Images - Photo - Primary - Photo - Primary - Photo - Primary - Photo - Primary - Photo - Primary - Photo - Primary - User 9 - Installation Instructions - Logo Image --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/cometic-amc-390-401-gen-3-v8-030in-mls-cylinder-head-gasket-4-250in-bore) > Updated: 2026-06-27
