Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 provides strong sealing for high‑output engines. It fits a 4.200 in bore and is offered in a nominal 0.040 in thickness with a compressed operating thickness of 0.040 in, compatible with valve‑pocketed bores and steam‑hole head designs. The gasket uses embossed stainless steel outer layers coated with Viton and an uncoated stainless shim center to resist corrosion, accommodate thickness variation, distribute load evenly, and lower clamp load to reduce bore distortion.
