Premium Ceramic Headers for Big Block Chevy

Take your Big Block Chevy powered 1968-1991 GM truck or SUV to the next level with these FlowTech metallic ceramic coated headers. Ceramic coating is the gold standard for exhaust performance, offering superior heat retention that keeps under-hood temperatures lower while increasing exhaust gas velocity for better scavenging. These headers are designed to handle the massive torque output of the 396 and 454 engines.

Why Choose Ceramic Coated Headers?

  • Thermal Efficiency: Metallic ceramic coating reduces engine bay heat.
  • Durability: Highly resistant to corrosion and thermal fatigue.
  • Primary Size: 1.75-inch primaries for excellent torque.
  • Collector: 3-inch collector for high-flow exhaust exit.
  • Fitment: Designed for 1968-1991 GM Full-size Trucks and SUVs.
  • Complete Kit: Gaskets and hardware included for installation.

These headers are not just about looks; they are a performance-driven upgrade that improves the longevity of your engine components by managing heat more effectively. The full-length design is specifically tuned to enhance the power band of the Big Block Chevy, providing the grunt you need for towing or off-road performance. With a focus on precision fitment, these headers install cleanly into your GM truck, ensuring you spend less time in the garage and more time on the road. For high-quality automotive performance parts that you can trust, look no further than GGCRACING.
