Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 provides dependable sealing for engine rebuilds. It fits a 4.200 in bore and has a nominal 0.027 in thickness, with valve pocketing and steam holes included for practical installation. Constructed from embossed stainless steel layers with Viton‑coated outer faces and an uncoated center shim, the gasket resists corrosion, allows thickness variation through shim selection, distributes clamping load, and reduces clamp load to limit bore distortion.
