Cometic's MLS cylinder head gasket for the GM LSX Gen‑4 small block V8 is a .056in multilayer steel gasket with a 4.060in bore and provisions for 1/2in and 3/8in studs on the right-hand side. HP shim technology raises clamp load around the combustion chamber to improve sealability on open‑deck blocks. Embossed outer layers pair AMP coating and an uncoated stainless shim to conform load distribution, require less clamp load, reduce bore distortion, and use Viton for harsh sealing environments.
