1967-87 Chevy/GMC Truck headers for automatic transmission. 1-5/8, .065 wall thickness, CNC, mandrel bent primary tubes. For optimal flow and CNC laser cut flanges, 3" slip fit collectors. These headers fit perfectly without dimpling the primary tubes around the steering box. Long tube design provides awesome low, end torque and street performance. Recommended for use with ACCEL shorty header plugs.
