Sanderson JaysterSBC178 Headers Small Block Chevy

The JaysterSBC178 is named after Sanderson header designer and custom fabricator Jay Wangerine. The Jayster offers a whole new take on the classic lakes-style outside chassis header. The unique four-into-one design offers an eye-catching addition to any roadster or highboy.

NOTE: Dimensions provided are for standard (typical) applications. For wider frames/bodies, such as 40's pickups, please CALL US for assistance. We can adjust the dimensions to fit virtually any chassis/body width (extra charges may apply).

Available in thermal ceramic coating or plain steel.

Comes with all hardware necessary for installation.

NOTE: Turnout tip, Finned Blockoff Plate, and underchassis adapters sold separately

The use of PowerCaps should be considered for all applications using under chassis exhaust piping.

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.

WARRANTY:



Limited 5-Year Warranty

NOTES:

   1. Sanderson 5-yr Warranty: The Patented Leak-Free Design that Sanderson Headers offer 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!
   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.
