Unleash Dominant Power in Your A-Body or B-Body LS Swap with Hedman Hedders

Transform your 1968-1972 GM A-Body (Chevelle, GTO, 442, Skylark) or 1971-1976 GM B-Body (Impala, Caprice, LeSabre, Delta 88) with an LS engine conversion using these high-performance Hedman Hedders long tube headers. Engineered for a precise fit and maximum exhaust flow, these headers are essential for extracting every ounce of horsepower and torque from your modern LS powerplant. Experience a significant boost in engine responsiveness and a commanding exhaust note.

Advanced Design for LS Swaps

  • Primary Tube Diameter: 1.875 inches for superior exhaust gas scavenging
  • Collector Size: 3-inch collector for unrestricted exhaust flow
  • Material: Durable Stainless Steel construction for long-lasting performance
  • Finish: Natural (uncoated) for a clean look or custom coating preparation
  • Engine Application: Optimized for GM LS-Series engines

Hedman Hedders has meticulously designed these long tube headers to ensure optimal clearance and performance in your A-Body or B-Body LS swap. The extended primary tubes promote efficient exhaust pulse extraction, dramatically reducing back pressure and allowing your LS engine to breathe more freely. This translates directly into increased horsepower and torque across the entire RPM range. Constructed from high-quality stainless steel, these headers offer exceptional resistance to corrosion and high temperatures, guaranteeing reliability and a long service life. The uncoated finish provides versatility for those who prefer a raw metal look or wish to apply a custom ceramic coating.

Vehicle Fitment

  • Fits 1968-1972 GM A-Body (Chevrolet Chevelle, Pontiac GTO, Oldsmobile 442, Buick Skylark) with LS-Series engine swap
  • Fits 1971-1976 GM B-Body (Chevrolet Impala, Caprice; Pontiac Catalina, Grand Ville; Oldsmobile Delta 88, 98; Buick LeSabre, Electra) with LS-Series engine swap

Invest in Hedman Hedders for a proven performance advantage. These headers deliver the ideal combination of power gains, precise fitment, and enduring quality for your LS-powered classic.
