The Cometic StreetPro top-end gasket kit for Chevrolet 350 Gen‑1 small-block V8 (4.100in bore, .040in MLS head gasket) delivers the gaskets and seals needed for a carbureted top-end rebuild. StreetPro kits feature MLS, AFM, aramid fiber and Armor Clad materials; MLS gaskets use embossed AMP-coated outer layers and an uncoated stainless shim to handle varied surface finishes, reduce clamp load and avoid the need for extra sealer.
