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:

  1. 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.
  2. Then, also apply a thin smear of silicone gasket maker on the opposite side of the adapter plate that will contact the cylinder head.
  3. Let the silicone fully dry overnight.
  4. Install the headers and the adapter plates onto the cylinder heads.
  5. Run the engine long enough to reach normal operating temperature for a few minutes.
  6. Let the engine cool and re-tighten the header bolts.

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.
