Cometic’s MLS head gasket for Volvo B23 engines is a 0.040" compressed-thickness, multi-layer steel gasket with a 97mm bore, featuring embossed outer layers coated with Viton. Designed to seal high-output engines without additional sealants, the MLS construction handles dissimilar head and block materials, resists corrosion, and provides the ability to rebound under load while helping distribute clamp forces across the sealing area.
