PRODUCT DESCRIPTION
Fits: 67-76 A, 62-74 B & 70-74 E Body
*67-76 A-body applications with Torsion bar suspension will require a Motor Plate to locate the engine.
Cylinder Head Studs: Head studs may be used on the Passenger-side, however, the header tubes will not clear the cylinder head studs below the #3, #5 and #7 cylinders on the Drivers-side. We recommend ARP bolts for clearance in these areas.
STRAIGHT PLUGS use header #400SR-218 ...Same header design, however this header will be clearanced (dimpled) in appropriate tubes to clear straight spark plugs.

3/8" thick Flanges, laser-cut, contoured for a leak free fit
Under chassis design: Above the steering center link design offers maximum header to ground clearance

Torsion bar removal: Not required in B & E-body applications, however, removal recommended in A-body applications
Header Material: Constructed of 16 gauge mild steel tubing. Mandrel bent on sophisticated computer controlled bending machines for precise fit and uninterrupted exhaust flow. The mandrel bending process maintains a constant inside diameter of the tube for a smoother finish with no restriction of flow and no crimping of the tubes.
