Athena Cooper Ring head gasket Volvo B23-B230

Athena Cooper Ring head gasket – hard stuff in soft package.

Strong head gasket for heavy use in tuned engines
Athena Cooper Ring has been a record breaker in sales for years, due to the way it combines the best features from multiple gasket types. Strong metal rings around the cylinders keep your cylinders sealed under the most challenging circumstances, without the need to do special machining (such as you do with flame rings).

Around the coolant and oil ports, the soft organic gasket with added silicone beading keeps the seal easier and more reliably than traditional MLS metal gasket.

Optimal head gasket for high performance / high boost engines.

• Recommended solution for high power engines
• Always make sure the block and head surface are clean, straight and in good condition before assembly
• Consider stronger ARP bolts in high output builds to prevent the stretch of oem bolts.
