Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 offers reliable sealing for high‑output engines. It fits a 4.200 in bore and is nominally 0.066 in thick, with valve pocketing and steam holes for common head setups. Built from multiple embossed stainless steel layers with Viton‑coated outer faces and an uncoated center shim, the gasket resists corrosion, accommodates thickness variation, evens sealing load, and requires less clamp load to reduce bore distortion.
