This high-performance gasket features a compressed thickness of .027 inches and is designed for a 4.570-inch bore diameter, making it ideal for custom engine builds and performance applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability under high-pressure and high-temperature conditions

  • 4.570" bore diameter accommodates various big block configurations
  • Undersized water ports designed specifically for aftermarket cylinder heads, allowing for custom port matching and coolant flow optimization

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Best prison the Internet and quick order fulfillment. Glad to have found Autoplicity!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.
