Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 is made for reliable sealing in performance rebuilds. It fits a 4.200 in bore and has a nominal 0.032 in thickness with valve pocketing and steam holes to match common head designs. Featuring multiple embossed stainless layers with Viton‑coated outer faces and an uncoated shim, the gasket resists corrosion, allows shim variation for thickness needs, evens load distribution, and needs less clamp load to help avoid bore distortion.
