• Ideal for aluminum heads, aluminum blocks, and cast iron blocks
• Made in the USA

Cometic gaskets are designed to meet the demands of modern high-performance engines where precision sealing is critical. The MLS technology allows the gasket to rebound and maintain seal integrity even under extreme cylinder pressures and thermal cycling. Sold as a pair for Twin Cam applications.
