Cometic, EST engine gasket kit. 3-1/2" bore

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 necessary gaskets in one package for engine reassembly.
This EST gasket set contains .040" thick MLS (Multi-Layer Steel) head gaskets, eliminating the use of O-rings for alignment dowels.
The base gaskets are made of .020" thick single layer steel (SLS). They have .005" of 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.
