Cometic MLS cylinder head gasket for Chevrolet Gen‑1 Small Block V8 (.056 in) with a 4.200 in bore and 18/23° head profile. Multiple embossed stainless layers use AMP coating on the faces and an uncoated center shim to maintain thickness and rebound. Viton-coated outer layers handle harsh sealing surfaces while steam holes and round bores aid coolant venting and reduce clamp load and bore distortion.
