Head gasket BSA STARTFIRE 250 250 1966 1970 Athena head gasket

The head gasket is a complex and fundamental technological component. To meet the continuous needs of the market, Athena subjects the head gaskets to intense control tests, both during the design phase and during the bench tests. The Athena head gasket can be produced using different technologies, for example metal / elastomer combinations or multilayer with steel materials and Athena coating. Choosing an excellent quality gasket is the first step towards the reliability of your engine.
Depending on the type, it is subjected to:
1. High precision cutting
Through the latest generation lasers it is possible to obtain a high degree of precision and purity of the cut, totally eliminating production burrs. These can in fact cause infiltration of various elements (oil, water, compression gas), compromising the functioning of the engine.
2. Relief alignment
This solution increases the elasticity of the gasket during operation, ensuring an excellent seal over time, even in extreme conditions. On the contrary, a misalignment of the blades would cause an immediate flattening of the gasket, eliminating the elastic memory function and the consequent loss of compression.
