1960–1983 Ford Inline-Six Exhaust Header
A freer-flowing exhaust path can give a classic Ford inline-six a deeper tone and a more responsive feel while replacing the heavy factory-style exhaust manifold. This stainless steel header is designed for the listed 1960–1983 Ford applications equipped with 144, 170, 200, or 250 CID inline-six engines. Review the vehicle and engine table before ordering, especially if the car has non-original engine mounts, steering parts, air-conditioning equipment, or a modified exhaust system.

Key Features
- Designed for listed Ford applications using 144, 170, 200, or 250 CID inline-six engines.
- Stainless steel construction with a mirror-polished finish.
- Individual header runners provide a less restrictive exhaust path than the factory-style cast manifold.
- 2.00-inch outlet provides a defined connection point for the downstream exhaust system.
- 7/16-inch cylinder-head flange and 3/8-inch outlet flange.
- Suitable for owners replacing a damaged factory manifold or building a sound- and flow-focused exhaust system.
Built for Better Flow and Sound
The factory cast exhaust manifold collects the cylinders in a compact, heavy assembly. A tubular header separates the exhaust paths before they merge, helping exhaust gases move through the system with less restriction.
On a naturally aspirated Ford inline-six, the most noticeable changes can include a sharper exhaust note, a deeper tone, and a more responsive feel as engine speed rises. The final result depends on engine condition, carburetor and ignition setup, muffler choice, pipe layout, and the quality of the installation.
A header alone should not be treated as a guaranteed horsepower upgrade. It works best as part of a properly matched exhaust system with sound engine, fuel, and ignition settings.
Factory Manifold vs. Stainless Steel Header
| Area | Factory-Style Manifold | FLASHARK Header |
|---|---|---|
| Construction | Compact cast design | Tubular stainless steel design |
| Exhaust Path | Cylinders merge close to the head | Individual runners merge farther downstream |
| Sound | Quieter, factory-style tone | Deeper and more pronounced inline-six tone |
| Installation | Matches the original exhaust layout | Requires clearance and downstream connection checks |
How This Header Fits the Exhaust Path
This component replaces the engine-side exhaust manifold and ends at a 2.00-inch outlet. Compare that outlet with the existing headpipe, muffler system, and any previous exhaust modifications before beginning the installation. A downstream adapter or exhaust-shop work may be needed when the existing system does not match the header outlet.
This is an exhaust header, not a complete catback system. Muffler choice and the remainder of the exhaust determine much of the final volume, drone level, and overall tone.
Installation and Exhaust-Leak Prevention
- Work only when the engine and exhaust system are fully cool.
- Inspect the cylinder-head sealing surface and remove old gasket material before fitting the header.
- Position the header without forcing it against the starter, steering, transmission linkage, body, or other components.
- Align the downstream exhaust before final tightening so the system does not place side load on the header.
- Check all joints for leaks after the first heat cycles and inspect the fasteners again after the system has cooled.
- Professional installation is recommended when fabrication, clearance adjustment, or downstream exhaust work is required.
Who This Header Is Best For
- Owners of a listed classic Ford with a 144, 170, 200, or 250 CID inline-six engine.
- Drivers replacing a damaged or restrictive factory-style exhaust manifold.
- Builders who want a deeper inline-six exhaust tone and a less restrictive exhaust path.
- Owners prepared to inspect header clearance and match the downstream exhaust connection.
Who Should Choose a Different Header
- Ford 300 CID or 4.9L inline-six owners.
- Vehicles outside the listed year, model, and engine combinations.
- Vehicles that must retain an original-style exhaust manifold.
- Owners who require guaranteed no-adjustment installation.
- Vehicles that require product-specific emissions certification for road use.
Emissions and Street-Use Notice
Exhaust modification requirements vary by vehicle configuration and location. Do not assume that an aftermarket header is approved for every road-use or emissions-controlled application. Check the requirements that apply to the vehicle before installation, and retain any required emissions equipment.
