The Cometic MLS cylinder head gasket for GM LT1/LT4 Gen‑II small block V8 (.066 in, 4.060" bore) with valve‑pocketed bores uses HP shim technology to increase clamp load around the combustion chamber and improve sealability. Comprised of multiple embossed AMP-coated layers and an uncoated stainless shim layer, the gasket distributes load while requiring less clamp load and reducing bore distortion. Coated on both sides with Viton for enhanced sealing.
