Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 provides dependable sealing for rebuilds and performance engines. It fits a 4.200 in bore with a nominal 0.045 in thickness and includes valve pocketing and steam holes for practical compatibility. Made from multiple embossed stainless layers with Viton‑coated outer faces and an uncoated center shim, the gasket resists corrosion, allows center‑layer thickness variation, evens sealing load, and requires less clamp load to help reduce bore distortion.
