Cometic Gen-6 MLS head gasket for 502ci Big Block V8 (4.470" bore, .060" compressed) uses multiple embossed stainless steel layers with Viton-coated outer faces to withstand harsh sealing environments. The multi-layer design rebounds under load, requires no sealants, and is suitable for aluminum-to-aluminum or aluminum-to-iron applications. The uncoated center shim layer can be varied for thickness, helping distribute clamp load and reduce bore distortion.
