High-Flow Sealing for Race Engines

When you have ported your Small Block Chevy heads to 1.550-inch square ports, standard gaskets will restrict airflow and cause sealing failures. The Fel-Pro 1405 exhaust header gasket is specifically designed to accommodate larger race-spec ports. Featuring a high-strength steel core laminate construction, these gaskets provide the durability required for high-RPM, high-heat racing environments.

Engineered for Performance

• Race-Ready Sizing: Optimized for 1.550-inch square ports to match ported cylinder heads.
• Steel Core Laminate: Provides exceptional structural integrity and heat resistance under heavy load.
• Leak-Free Performance: Designed to withstand the high cylinder pressures of modified engines.
• Perfect Alignment: Ensures a smooth transition from the exhaust port to the header flange.

These gaskets are essential for builders who demand precision and reliability. An improper gasket match can create steps in the exhaust path, causing turbulence and reducing horsepower. By using the Fel-Pro 1405, you ensure that your exhaust flow remains uninterrupted while maintaining a perfect seal against the cylinder head. Sold as a pair, these are the go-to choice for serious engine builders. Find these and other high-performance sealing solutions at GGCRACING.
