1970-1972 Monte Carlo LS 1-7/8in Ceramic Coated Long Tube Headers
For anyone tackling an LS engine swap in a 1970 to 1972 Monte Carlo finding headers that clear the stock frame rails and maintain a reliable seal often slows progress. These 1970 to 1972 Monte Carlo LS 1 7/8 Ceramic Coated Long Tube Headers are purpose built for LS installs in this chassis providing a precise match to factory frame rail contours while optimizing exhaust flow. Constructed from thick gauge mild steel and finished with a ceramic barrier this design controls underhood temperatures and stands up to corrosion during spirited runs. Installation moves quickly thanks to forgiving flange tolerances and comprehensive hardware so the swap can move straight to tuning and test fits without guesswork.
Optimized Exhaust Flow with One and Seven Eighths Inch Primaries
Primary tubes measuring one and seven eighths inches in diameter reduce backpressure to enhance scavenging and deliver gains in horsepower and torque across the rpm band. By smoothing the transition of exhaust pulses, this tube size supports efficient gas evacuation and improves throttle response under load. The uniform bore profile minimizes turbulence inside each runner, allowing the engine to breathe more freely during acceleration. Overall, the design translates into a more responsive power curve suited to both street cruising and spirited driving.
Ceramic Coating for Underhood Temperature Control
The ceramic barrier finish acts as a thermal shield, reflecting heat back into the exhaust stream and cutting down radiant temperatures beneath the hood. This heat containment safeguards wiring harnesses, fuel lines, and intake components from premature aging caused by excessive heat soak. By retaining warmth in the exhaust gases, the coating also promotes faster scavenging at low engine speeds, improving torque response off the line. Consistent thermal management during extended runs ensures stable performance without sudden heat spikes.
Precision Flange Machining Ensures a Leak Proof Seal
Each flange is machined to a three eighths inch thickness and ground flat to create a perfectly level sealing surface against the cylinder head. This precision machining prevents warping during repeated heat cycles, eliminating uneven contact points that can lead to exhaust leaks. The uniform surface ensures gaskets compress evenly, maintaining a reliable seal even under high boost or heavy load conditions. As a result, installers gain confidence in long lasting sealing performance without the need for constant retightening.
Durable Steel Construction with V Band Clamps for Service Ease
Built from thick gauge mild steel, these headers withstand vibration and road shock typical of a classic Monte Carlo chassis, resisting cracking and fatigue from cyclical heating and cooling. Included V band clamps and Seal-4-Good gaskets streamline collector connections and guarantee a tight seal without custom welding. The clamp design enables quick release and reassembly when servicing or swapping components, reducing downtime in the garage. This combination of robust materials and service-friendly hardware delivers durability and ease of maintenance.
Engineered for a precise fit and consistent performance in your Monte Carlo LS swap.
