Sanderson Headers CC4DP Small Block Chevy D-Port Heads

CC4DP Header Set, Small Block Chevy

The CC4DP is a shorty header with a swept-forward driver’s side collector to clear the steering box on 1935–40 Ford cars and trucks and 60s Ford pickups using a small block Chevrolet engine with angle plug, D-port cylinder heads.

The design of the CC4DP allows for ample steering gear clearance for both standard and Saginaw steering boxes, though this application requires an offset motor mount on the driver’s side. The CC4DP is compatible with GM-spec angle plug and D-port heads. Shorter header spark plugs are required.

Please review the “What is a D-Port” and “Vortec-Style Heads” information tabs for cylinder head compatibility.

FINISH:

Our Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. We apply a multi-layer inside and outside aluminized ceramic coating in-house and 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.

OPTIONS:

Our Aluminized Ceramic Coating is available and RECOMMENDED on all Sanderson Headers. We apply a multi-layer inside and outside silver ceramic coating in-house to meet our high standards of quality, and polish the coated header to a high luster. This coating provides aerospace and military technology to your vehicle to control the heat in your engine bay, improve cylinder scavenging of exhaust gases, and increase 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.
