Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 provides durable sealing for rebuilds and high‑output engines. It fits a 4.200 in bore and is nominally 0.098 in thick with valve pocketing and steam holes for proper head fit. Constructed from embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim center, the gasket resists corrosion, accommodates thickness variation through shim selection, evens clamp load across the sealing area, and reduces required clamp load to help limit bore distortion.
