Headers - SBC D-Port Block Hugger Style

FLOWTECH Headers - SBC D-Port Block Hugger Style are designed specifically for small-block Chevy engines that require enhanced performance while maintaining compact underhood clearance. These headers are essential for engine builders looking to upgrade their exhaust systems, as they facilitate the efficient evacuation of exhaust gases, which is crucial for maximizing horsepower.

The D-port design utilizes FLOWTECH's advanced primary tube geometry to optimize scavenging, allowing exhaust pulses from one cylinder to assist in the evacuation of gases from the next. This design minimizes residual combustion chamber pressure and enhances cylinder breathing. Constructed from high-quality steel tubing with mandrel-bent bends, these headers reduce turbulent flow restrictions and improve exhaust velocity.

Ideal for street machines, vintage restorations, and engine swaps, the block hugger configuration keeps the headers close to the engine block, ensuring compatibility with power steering pumps, air conditioning compressors, and other accessories. This makes them a practical choice for those working with limited space in their engine bays.
