The Cometic GM Gen-4 LS3 small block V8 Top End gasket kit (no head gasket) supplies the seals and gaskets needed for a street-style top-end rebuild. StreetPro kits prioritize quality materials—MLS, AFM, Aramid Fiber and Armor Clad—while omitting the head gasket. Components are tested on the street and dyno, and the kit balances cost with reliable gasket materials for routine rebuilds and street-rod projects.
