Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 supplies reliable sealing for rebuilt and upgraded engines. It fits a 4.200 in bore and has a nominal 0.056 in thickness with valve pocketing and steam holes for common head arrangements. Constructed from embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim layer, the gasket resists corrosion, allows center‑layer variation to meet thickness needs, evens load distribution, and needs less clamp load to help prevent bore distortion.
