Cometic engine gasket kit, 5-speed EST. Diameter 3-1/2"

This EST (Extreme-Sealing-Technology) gasket kit includes all gaskets, seals and O-rings used on this model, including the primary gaskets. It is the easiest way to carry out a complete overhaul and have all the gaskets needed in one package for engine reassembly.
This EST gasket set contains .040" thick multi layer steel (MLS) cylinder head gaskets, eliminating the use of O-rings for alignment pins.
The block gaskets are single layer steel (SLS) .020" thick. They have .005" high-temperature Viton rubber on both sides and are the strongest on the market.
The rocker cover gaskets are also .020" thick SLS. They do not leak, extrude, break or become brittle over time.
The exhaust gaskets do not obstruct exhaust gas flow or fray in the exhaust port.
The valve seals use Viton rubber and outer springs for a perfect seal.
