Cometic MLS head gasket for GM USAC Midget, .040in multilayer steel construction with a 4.155in bore. Multiple embossed stainless-steel layers feature Viton-coated outer faces and an uncoated stainless shim for rebound and corrosion resistance, providing durable sealing for aluminum-to-aluminum or aluminum-to-iron pairings. The MLS design seals without sealants, reduces required clamp load to limit bore distortion, and evens load across the sealing area.
