This Cometic multi-layer steel (MLS) head gasket is specified for Chrysler R3 small block race blocks with a 4.165" bore and .040" thickness for W7/W8/W9 heads. Constructed from multiple embossed stainless layers with Viton-coated outer faces, the gasket resists corrosion, rebounds under load and conforms across sealing surfaces. MLS design reduces clamp load needs and is suited for high-output engine sealing.
