The CC16 header set fits 1967-69 Camaro and Firebird, and 1968-72 Nova applications using small block Chevrolet engines.
The CC16 fits applications using stock motor mounts and is compatible with both manual and automatic transmissions. The CC16 works on “most” GM-spec angle plug cylinder heads (ZZ4, LT1, ZZ6, 292, Bowtie, etc.). Compatible with some aftermarket rack and pinion steering setups too (see images)!
NOTE: The standard CC16 does NOT clear factory Air Conditioning on Camaro or Nova. The evaporator box on the firewall interferes with the header. Please specify if the vehicle has factory AC to ensure you receive the correct right-side header.
Product ID Note: Although some Sanderson dealers offer the CC16 as part #CC16AP, it does not fit all aftermarket angle plug cylinder heads. The standard CC16 and CC16AP are identical header sets. Only on D-Port cylinder head applications (ZZ4, ZZ6, etc.) is there a difference. For these applications, the CC16DP is manufactured using the proper D-port header flange and includes the “DP” suffix in the product SKU.

Our Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, We apply a multi-layer inside and outside aluminized ceramic coating in-house and then polish 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.
Vortec-Based and BluePrint Style Heads
This informative article was written by Sam of Century Performance Center
NOTE: This issue concerns STRAIGHT PLUG Vortec-style small block Chevy cylinder heads, including the BluePrint heads
Vortec-style (and this includes some non-GM aftermarket) cylinder heads use a different spark plug location than common non-Vortec cylinder heads. Vortec-based heads move the spark plugs further from the center of the chamber and closer to the exhaust valve. This can cause a header clearance issue because it changes the spacing between the two center spark plugs, moving them 1/2″ closer together. On exhaust headers that have tight bends near the cylinder head (for example, the Sanderson CC158 header shown below), the dimpling of some tubes is required for spark plug clearance. Dimpling of other tubes is sometimes required on other header designs affected by the spark plug location and up-down angle.
BluePrint cylinder heads are based on the Vortec spark plug locations. However, the BluePrint heads are manufactured with a raised exhaust port exit. This changes the up-down angle of the spark plug in addition to the center-to-center distance of the two center spark plugs. Dimpling locations vary slightly between common Vortec-based and BluePrint header applications.
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 the image below). Additionally, one of the reasons we ask for the cylinder head brand, type, and the part number is that every Vortec-style cylinder head does not utilize the same spark plug location and angle. Having accurate information allows us to ensure that the proper dimpling is applied to the Sanderson header set for spark plug boot clearance during the manufacturing process.

What is a D-Port?
This article was provided by Sam of Century Performance Center, Inc.
We often see confusion in what is considered a D-Port cylinder head for small block Chevrolet engine applications. 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. As shown in the graphic below, the d-shape easily fits within the common round or square port flange opening.
Where other header manufacturers use a typical flat header flange and gasket for sealing, the patented raised flange design of the Sanderson Headers requires different flanges for different small block Chevy exhaust port shapes. Other header flanges will often block the top of the exhaust port on D-port heads. When using a Sanderson D-Port flange the port is not blocked. However, using the wrong flange with a Sanderson header may expose open areas that will not seal, creating an exhaust leak.
- Using a D-port flange on a common GM head (standard round, square, or D-shaped port), the header port flange open is larger (taller opening) than the sealing area around the exhaust port (additional details below, comparing two BRODIX Track 1® cylinder heads)
- Using a standard Sanderson header flange on a D-port cylinder head has a similar problem, where the cylinder head exhaust port opening may extend above the raised flange sealing area, again creating the possibility of an exhaust leak.
Here is an example of a small block Chevrolet D-port cylinder head that requires the Sanderson D-Port header flange.
