Sanderson Headers CC134AP-SEC Small Block Chevy

CC134AP-SEC Header Set, Small Block Chevy

The CC134AP header set is a large tube design for 1927 and up automobiles and trucks using small block Chevrolet engines. It fits aftermarket Mustang II, Vega, and rack-and-pinion front suspension kits, including Heidts, TCI, and Chassisworks chassis, and clears most motor mount styles, tie rods, and steering rods.

This version is designed for angle plug cylinder heads—identified by the "AP" suffix—ensuring proper spark plug clearance in tight engine bays. It is compatible with GM-spec angle plug heads and many aftermarket options.

The CC134 is one of our most popular small block Chevy headers. Its features include a 1-3/4″ primary tube diameter and a 3.0″ collector for all but the most radical performance engines. Compatible with straight or angle plug cylinder heads, it is the most compact true-performance header offered today.

OPTIONS:

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.

What is a D-Port?

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.

Examples:

1. 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)
2. 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.
