Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 offers reliable sealing for engine rebuilds. It fits a 4.200 in bore and is nominally 0.120 in thick with valve pocketing and steam holes for common head arrangements. Made from multiple embossed stainless layers with Viton‑coated outer faces and an uncoated shim layer, the gasket resists corrosion, allows center‑layer thickness variation, distributes load evenly across the sealing surface, and reduces clamp load to help minimize bore distortion.
