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.

Sanderson Headers
Sanderson Headers for street rods, classics, and muscle cars.
Ford 4V vs 2V Heads
4V vs 2V Ford Cylinder Heads:
Sanderson headers for the Ford 351C, 351M, and 400 engines feature flanges for the larger port four-barrel (4V) cylinder heads. If using two-barrel (2V) cylinder heads, Sanderson part #2BBLFC copper adapter plates are required to ensure proper sealing.
When installing Sanderson headers with the 2BBLFC adapters, we recommended this installation procedure:
- Follow the standard installation instructions on our website that describe a thin “smear” of silicone gasket maker around the exhaust ports on the header flange. This will contact the adapter plate.
- Then, also apply a thin smear of silicone gasket maker on the opposite side of the adapter plate that will contact the cylinder head.
- Let the silicone fully dry overnight.
- Install the headers and the adapter plates onto the cylinder heads.
- Run the engine long enough to reach normal operating temperature for a few minutes.
- Let the engine cool and re-tighten the header bolts.
Sanderson Warranty
Limited 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.
