The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 with Vortec heads (4.165in bore) offers a 0.030" compressed operating thickness and installs sealant-free for reliable sealing in high-output small-block applications. Its construction pairs embossed stainless outer layers coated with Viton and an uncoated stainless center shim to resist corrosion, rebound under load, and distribute clamp forces to reduce bore distortion across dissimilar head and block materials.
