The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 with Vortec heads (4.165in bore) is a multi-layer steel replacement designed for high-output small-block builds. It uses a compressed operating thickness of 0.027" and installs without sealants. Embossed stainless outer layers coated with Viton and an uncoated stainless shim provide corrosion resistance, rebound under load, and even load distribution to reduce bore distortion and tolerate aluminum-to-aluminum or aluminum-to-iron interfaces.
