The Cometic MLS head gasket for GM Dart/Brodix Small Block V8 (.066in spec, 4.270in bore, 4.500in bore center) is made from multiple embossed stainless-steel layers with Viton-coated outer surfaces and a variable center shim.

It conforms sealing loads to reduce bore distortion and is intended to seal high-output engines without supplemental sealants.
