Sanderson's patented flange design requires no gaskets

The Sanderson C32DP header is full length, 1-5/8″ primary tube header that is one of the most widely used in street rod applications. Providing ample spark plug clearance, the C32DP works with many stock steering gears, Vega, and rack and pinion setups IF THE STEERING SHAFT HUGS THE FRAME RAIL. Clears most starters and transmissions EXCEPT cast iron Powerglide.

  1. Designed with raised primary tubes to fit D-Port cylinder heads.
  2. Pre-’68 engines must use a spin-off oil filter adapter and filter.

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.

What is a D-Port?

We often see confusion in what is considered a D-Port cylinder head. The problem originates in the technical understanding of what constitutes a true D-PORT versus a D-shape. The D-Port roof extends well above the centerline of the exhaust port, whereas the D-shaped port fits nicely inside what is deemed a standard port dimension.


Vortec-Style Heads

NOTE: This issue concerns STRAIGHT PLUG Vortec-style cylinder heads

Vortec style (and this includes non-GM aftermarket) cylinder heads use a different spark plug spacing on the center two spark plugs. Many exhaust headers will require specific dimpling to ensure adequate spark plug clearance when used with the Vortec-style heads.

If unsure, please measure the center-to-center distance between the center pair of spark plugs on your heads. The standard distance is 4.5″ (11.43 cm) versus 4.0″ (10.16 cm) on the Vortec heads. See image below:

Install Notes

Installation Notes:

  • Pre-1968 engines require conversion to spin-on style oil filter.
  • Use of the short-style oil filter recommended on all applications for maximum clearance.  Use AC oil filter part number PF454 or other equivalent  filter brand and part number. An aftermarket oil filter the same size as the discontinued PF25 works perfectly. The PF454 is shorter than even the PF25 it replaced.


  1. The Patented Leak-Free Design that Sanderson Headers offer you is the only leak-free flange design on the market … Do Not Attempt To Use Flange Gaskets! The raised flange on the Sanderson Headers will buckle the gasket during tightening and actually cause a leak! Click here for 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 that is available for every Sanderson Header. Please read our tech article that thermal coatings and header wraps.

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.

* Extremely compact header designs which locate the collector in close proximity to the exhaust ports are very sensitive to engine tuning.
