SB Ford Flanges

IMPORTANT UPDATE: Our small block Ford header flange has been redesigned to accommodate both standard rectangular and square exhaust port designs. This new flange is compatible with 2.0″ mounting bolt spacing

We are keeping the content below for informational purposes.


We offer two primary header flange styles for small block Ford engines. The standard rectangular port flange and a square port flange with 2.0″ bolt spacing. Factory OE Ford heads use a 2.0″ bolt spacing. Some aftermarket small block Ford cylinder heads include both the 2.0″ and 3.0″ bolt spacing  Roush heads (SB427 for example) only use the 3.0″ bolt spacing.

The 3.0″ bolt spacing is a problem for thick-flange header sets because it makes installing the spark plugs virtually impossible, as shown in the images below. Only header sets built with thin 1/4″ – 3/16″ flanges are compatible with the 3.0″ bolt spacing.

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.

NOTE: Extra charges are incurred for headers ordered with the square port flange due to the additional manufacturing time required when building headers with the square port flange.

Below are two images showing the differences between the rectangular vs. square flange styles. The square flange shown utilizes the 2.0″: bolt spacing. 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.

Why Use PowerCaps?

Sanderson PowerCap displayFor those looking at the Sanderson Lakes-style Limefire and Jayster outside chassis headers for their street rod, here is a tech tip that might save some grief, frustration, and possible damage to the headers!

You may already know that the Sanderson lakes-style headers are available with or without connections for an under-chassis exhaust system. The ability to have a throaty open exhaust or a quiet and capped lakes-style header using an under-chassis system has been something Sanderson has offered since the original design.

We have found that on stock or mild street rod engines, there is not much of an issue if following the normal installation instructions. However, on applications making decent horsepower, it is possible to damage the header or header coating near the end of the collector where the under-chassis adapter connection is located. The cause of this problem is the turbulence created by the limited distance of dead space just after the under-chassis connection and the end cap on the header (when the header is capped and exhaust gasses are being routed through an under-chassis exhaust system). The turbulence in this area causes the EGT’s (Exhaust Gas Temperatures) to rise dramatically, and in certain applications, this could cause the temperatures to exceed the thermal capacity of the header coating—causing finish damage and discoloration. The problem only seems to occur on high-power engines and engines that are regularly operating at higher RPMs—for example, considerable highway driving on lower-geared vehicles.

The solution is relatively simple but adds cost to the header purchase. Sanderson designed a component called the “PowerCap” to solve this issue. The PowerCap slides into the collector tube and provides a smooth redirection of exhaust gas flow from the collector tube into the under-chassis exhaust tubing. The PowerCap bolts securely into your header using the end cap flange, thereby removing the turbulence area in the collector horn. Another benefit of using the PowerCaps is improved horsepower by improving airflow into the under-chassis exhaust. Although the PowerCaps are recommended for higher horsepower applications, they also benefit all applications using the under-chassis exhaust connection.

PowerCaps capture hidden horsepower on applications using under-chassis exhaust connections. Under-chassis adapters allow you to run a quieter under-chassis exhaust system, and adding the PowerCaps increases power and extends the life of your headers.

Installation Notes

  1. The Patented Leak-Free Design on Sanderson Headers provides the only leak-free flange design on the market … Do Not Attempt To Use Flange Gaskets! The raised flange on tube-style Sanderson Headers will buckle the gasket during tightening and actually cause a leak!  It is only OK to use a header gasket on the cast-series header sets (QP1000 and QP2000) Click here for the header installation procedure.
  2. Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser’s responsibility to verify local regulations for compliance.
  3. Wrapping your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating which is available for every Sanderson Header. For additional information on why using header wraps is a problem, please read this tech article by Century Performance Center which addresses thermal coatings and header wraps.

Header Warranty

Sanderson Header WarrantyLimited 5-Year General Warranty

Sanderson Street Rod Headers strives to supply our customers with the highest quality parts and services available in the street rod industry. In keeping with this, we warrant and will repair or replace, at our option after an inspection in our facility, any of our products that are found by us to have failed due to defects in either material or workmanship.  This warranty is activated by the return of the Warranty Card enclosed with every pair of headers and is effective for FIVE YEARS * from the date of purchase as indicated on the original invoice.

This Warranty does not cover products that fail due to improper motor tuning, alteration, disassembly, or damage caused by racing, misuse, neglect, abuse, improper installation, and/or accident, or when used on applications for which they were not designed or approved. We are specifically not responsible for the costs of removal, installation, transportation, destruction of other components, inconvenience, loss of time, or other personal damages, or for any other associated costs including the application of aftermarket coatings applied by others. Sanderson Street Rod Headers shall not be liable for any and all consequential damages occasioned by the breach of any written or implied warranty pertaining to this sale in excess of the purchase price of the product(s) as found on the original invoice.

WRAPPING HEADERS WITH THERMAL TAPE VOIDS THE WARRANTY.

* Extremely compact header designs that 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. This includes header sets that utilize one of these headers as part of the set (part numbers CC4 and CC14 for example). The compact header side will hold a 2-year warranty. All other Warranty conditions apply.
