1-7/8 Ceramic Headers Optimized for 1977-1990 B-Body LS

Optimal exhaust flow meets reliable sealing courtesy of 1.875 inch primary tubes and precision crafted 3/8 inch thick flanges, boosting torque and horsepower for your 1977 to 1990 B body LS application. Reflective ceramic coating keeps engine bays cooler while the integrated V band collector and complete hardware kit ensure a leak free header install in minutes.

1-7/8 Inch Ceramic Coated Long Tube Headers for 1977-1990 B-Body LS Engines

When you retrofit an LS engine into a 1977-1990 B-body GM chassis, factory exhaust manifolds often restrict flow and rub against the frame rails. These 1-7/8 inch long tube headers with a ceramic coating deliver consistent primary runner diameter and a tight fit that clears crossmembers. Each header features 3/8 inch thick flanges to lock in a reliable seal at the head and an V band clamp collector that prevents leaks under load. Installation hardware is included for a plug and play swap so you can spend less time sourcing parts and more time tuning your engine.

Advanced Ceramic Coating for Efficient Heat Management

The ceramic layer applied to each mild steel header significantly reduces radiant heat transfer in the engine bay, keeping underhood temperatures in check. By reflecting thermal energy back into the exhaust stream, the coating helps maintain optimal gas velocity for improved scavenging and throttle response. This surface finish also resists oxidation and corrosion, ensuring the headers retain their performance characteristics over thousands of miles. As a result, you enjoy consistent power delivery without the heat soak that can degrade engine components and drivability.

Precision Machined Flanges for Leak Resistant Sealing

Each flange is plate-thickened to 3/8 inch and machined flat to guarantee uniform contact against the cylinder head. This robust sealing surface minimizes the risk of exhaust leaks, even under high boost or heavy load conditions, which translates to reliable backpressure control and fuel economy. The precision fit reduces the need for excessive gasket compression and maintains consistent torque readings during installation. Strong metal-to-metal contact also enhances gasket life, cutting down on maintenance intervals.

Engineered Fitment for 1977 to 1990 B Body LS Swaps

These long tube headers were specifically designed to clear common crossmember and frame-rail interference in 1977 through 1990 B-body GM chassis. With a uniform 1-7/8 inch primary runner diameter, they deliver balanced exhaust pulses across all cylinders, optimizing torque and horsepower across the rev range. Detailed tube routing ensures adequate ground and steering linkage clearance without cutting or bending factory components. The result is a seamless integration that honors the chassis geometry while unlocking modern LS power potential.

Complete Hardware Kit for Rapid Installation

Every purchase includes Seal-4-Good gaskets, essential mounting bolts, and V band clamps sized for the collector to eliminate the hassle of sourcing parts. Components arrive packaged together, matching the exact header dimensions to simplify alignment and torque procedures. This comprehensive kit approach reduces installation time and ensures each connection meets factory-style sealing standards. You'll spend less time hunting down fasteners or fittings and more time refining engine calibration and enjoying the drive.

These headers deliver a precise fit and lasting performance for your 1977 to 1990 B body LS swap.
