Cometic engine gasket kit, EST. Standard diameter

This complete EST (Extreme-Sealing-Technology) gasket kit includes all gaskets, seals and O-ring seals used on this model, including the primary gaskets. It is the easiest way to carry out a full overhaul and have all the necessary gaskets in a single package for engine reassembly.
This EST gasket set contains 0.040" thick multi-layer steel (MLS) cylinder head gaskets, which eliminates the use of O-rings for the alignment pins.
The base gaskets are single layer steel (SLS), 0.020" thick. They have 0.005" high-temperature Viton rubber on both sides and are the toughest on the market.
The rocker cover gaskets are also .020" thick SLS. They do not leak, extrude, tear 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.
