Cometic engine gasket set, EST. Diameter 3-1/2"

This EST (Extreme-Sealing-Technology) gasket set is complete and includes all gaskets, seals and O-rings used on this model, including the primary gaskets. It is the easiest way to carry out a full overhaul, as all the gaskets needed for engine reassembly come in a single package.
This EST gasket set contains 0.030" thick multi-layer steel (MLS) cylinder head gaskets, eliminating the need to use O-rings for the alignment pins.
The block gaskets are 0.020" thick single layer steel (SLS). They have 0.005" high-temperature Viton rubber on both sides and are the toughest on the market.
The rocker cover gaskets are also single layer steel (SLS) 0.020" thick. 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 external springs to guarantee a perfect seal.
