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.

WARRANTY:



Limited 5-Year

DIMENSIONS:

When sitting in driver's seat and engine in front of you, the LEFT header would be the Driver's Side on LH drive vehicles; coincidently, means the RIGHT header is on the passenger side. See the detail image above left that describes engine sides.

ADD ONS:

*Turnouts are the perfect compliment to our Limefire and Jayster series roadster headers. The Turnout Tips bolt directly to the collectors to enhance the open pipe look. Can be used with our without the blockoff plate.

*The Finned Aluminum Blockoff Plates are used on our Limefire series headers. A block plate is used in conjunction with our UCEA Under Chassis Exhaust Adapters.

*Our Under Chassis Exhaust Adapters allow you to connect your outside chassis headers to an under chassis exhaust system. Under chassis adapters allow you to run a quiter under-chassis exhaust system.
