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 is nominally 0.060 in thick with valve pocketing and steam holes for proper head fit. MLS construction uses multiple embossed AMP‑coated and uncoated stainless steel layers; outer layers are coated to handle harsh sealing environments while an uncoated shim layer allows thickness variation. The design evens load distribution and reduces clamp load to limit bore distortion.
