The Sanderson FF4 header fits a variety of street rods, cars, and pickups using small block Ford 351W engines. This is the most compact Windsor header design on the market and solves clearance problems in street rods, kit cars, and classic trucks. The FF4 clears most steering and chassis setups without a cross member directly below the center of the engine.

Sanderson’s Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, Sanderson applies a multi-layer inside and outside aluminized ceramic coating in-house and then polishes the coating to a high luster. This aerospace and military-grade technology adds excellent protection to your headers, while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases, and increases the longevity of your header investment.
When sitting in driver’s seat and engine in front of you, the LEFT header would be the Driver’s Side on LH drive vehicles; coincidentally, means the RIGHT header is on the passenger side. See the detail image above left that describes engine sides.

SB Ford Flanges
Sanderson offers some of their small block Ford headers in two flange styles—the standard rectangular flange, and the square port flange. A third flange style is available on some header sets for the Roush-style SB 427 cylinder heads. This is not a common flange design. Many aftermarket cylinder head manufacturers now use the square port shape on their products. However, that does not mean the square flange is required. The importance here is to ensure the header flange properly seals to the cylinder head. In most cases, the standard rectangular shape works perfectly, but on other heads, the square port flange is necessary. It is the customer’s responsibility to decide the correct flange for their application. Typically, the ONLY cylinder heads that accept a square port flange are those with either four mounting bolts per port (two are spaced wider apart to accommodate the wider port opening) or very specific cylinder heads that only offer the wider bolt spacing.
NOTE: Sanderson charges extra for headers built with the square port flange due to the additional manufacturing time required.
Below are two images showing the differences in the flange styles. Please use these images and the provided dimensions to ensure the proper flange is selected for your new Sanderson Headers from the drop down menu on the product details.

WRAPPING HEADERS WITH THERMAL TAPE VOIDS WARRANTY.
* Extremely compact header designs which locate the collector in close proximity to the exhaust ports are very sensitive to engine tuning. Improper air/fuel mix or timing of ignition and/or valvetrain can cause early failure due to excessive heat. For this reason, part numbers CC2 and CC3 are offered with a two-year Warranty period only. All other Warranty conditions apply.
