The Sanderson DD4 header fits Dodge 241-325 Hemi V8 engines in Model A and later chassis that do not have a cross member directly under the center of the engine. The DD4 drops straight down, and the collector is tight to the oil pan. If unsure of which engine you have, the Dodge Hemi and DD4 bolt pattern should measure 14-3/8″ center-to-center of the outer flange bolts (see image example). The DD4 is compatible with most steering setups.
Includes all hardware necessary for installation.
NOTE: For cylinder heads with 14¾” spacing, order part number DD5

OPTIONS:
Sanderson’s Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, Sanderson applies a multi-layer inside and outside aluminized ceramic coating in-house and then polishes 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.
