Optimized Sealing for D-Port Heads

D-port cylinder heads are a popular choice for Small Block Chevy builders looking to improve exhaust flow characteristics. However, they require a specific gasket shape to ensure a proper seal. The Fel-Pro 1406 exhaust header gasket is precision-cut for 1.530 x 1.630-inch D-ports, providing a perfect fit that prevents leaks and maintains optimal exhaust velocity.

Why Choose Fel-Pro 1406?

• D-Port Specific: Designed to match the unique shape of high-performance D-port heads.
• Steel Core Laminate: Offers superior crush resistance and thermal stability compared to standard gaskets.
• Durable Construction: Built to withstand the rigors of performance street and track use.
• Consistent Seal: Prevents exhaust gas leaks that can cause power loss and engine bay heat issues.

Using the wrong gasket on D-port heads can lead to significant sealing issues and potential exhaust leaks that are difficult to diagnose. The Fel-Pro 1406 ensures that your header flange is fully supported, providing a reliable barrier against the intense heat and pressure of the exhaust cycle. Sold as a pair, these gaskets are a must-have for any D-port engine build. For high-quality sealing components and expert advice on your next project, visit GGCRACING.
