Cometic MLS cylinder head gasket for the GM L18 Vortec 8100 Gen‑VII Big Block V8, .060in compressed thickness with a 4.350in bore for the left side. The gasket uses embossed stainless steel layers and Viton-coated outer surfaces for durable sealing in demanding heat and load conditions. An uncoated center shim accommodates thickness requirements while the MLS construction improves load conformity, reduces bore distortion, and works without additional sealants.
