Reliable Sealing for Crate Motors

Keep your crate motor running at its peak with the Allstar Performance header gasket, specifically designed for non-LS Fast Burn and similar D-port applications. This gasket provides a precise, reliable seal for Small Block Chevy engines, ensuring that your exhaust system operates at maximum efficiency without the risk of leaks or blown gaskets.

Technical Features & Benefits

  • Port Size: 1.520 x 1.510 inch D-port design.
  • Material: Steel core laminate construction.
  • Application: Ideal for SBC crate motors and Fast Burn heads.
  • Durability: Built to withstand high heat and vibration.
  • Fitment: Engineered for a perfect, leak-free seal.

Crate motors are a popular choice for their reliability and power, but they require the right supporting components to maintain that performance. This Allstar Performance gasket is manufactured with a steel core laminate that offers superior strength compared to traditional materials. It is designed to handle the specific thermal expansion and contraction of high-performance heads, preventing the common issue of gasket blowout. Whether you are installing new headers or replacing worn gaskets during a tune-up, this part provides the professional-grade reliability you need. Its precise dimensions ensure that you get a clean port match, which is essential for maintaining exhaust velocity and engine power. Make sure your crate motor build is protected with the right sealing technology. Discover more high-performance engine parts and accessories for your vehicle at GGCRACING.
