Cometic StreetPro top-end gasket kit for GM LS1/LS6 Gen-3 small-block V8 engines with a 4.040in bore and a .051in MLS cylinder head gasket. The kit includes the gaskets and seals needed for a head rebuild and uses MLS multilayer steel construction with AMP-coated embossed outer layers and an uncoated stainless shim. Embossed outer layers meet harsh sealing demands, require less clamp load and help limit bore distortion while improving load distribution.
