About This Product
This Cometic EST motor gasket kit for standard bore Panheads is exactly what you need when tearing into a 1948–1965 74-inch (1200cc) engine for a complete overhaul. Sold as a set, it includes every gasket, seal and O-ring required for the job, right down to the primary gaskets. The MLS .040-inch head gaskets eliminate the hassle of dowel pin O-rings entirely, while the SLS .020-inch base gaskets feature high-temperature Viton rubber coating on both sides for a bulletproof seal. Rocker covers get the same SLS treatment—no more weeping, tearing or brittle gaskets down the line. Exhaust gaskets flow freely without fraying into the ports, and the Viton valve seals with outer springs ensure zero leaks. Replaces OEM 17028-48.
