Ceramic Coated LT Long Tube Headers for 1975-1979 X-Body Nova and Ventura
When planning an LT swap into a 1975-1979 X Body Nova or Ventura, headers that maintain exhaust velocity, control bay heat and deliver precise port alignment are essential. The 1975-1979 X Body 1-7/8 LT Ceramic Coated Long Tube Headers use 1.875 inch mild steel primaries with a multi layer ceramic finish to reflect radiant heat into the exhaust stream. CNC formed 0.375 inch flanges match factory ports and pair with composite gaskets and V band clamps to seal under vibration and thermal expansion. Smooth MIG welded joints resist cracking across heat cycles; high grade bolts simplify fitment for LT series engines on Chevy Nova and Pontiac Ventura X Body chassis.
Enhanced Flow with 1.875 Inch Long Tubes
The equal-length 1.875 inch primary tubes are tuned to optimize exhaust velocity and scavenging across the LT engine's mid to high rpm range. By maintaining a consistent diameter from the head flange to the merge collector, these headers promote a uniform pulse wave that draws spent gases from each cylinder more efficiently. On the 1975–1979 X-Body chassis, this translates into a measurable torque gain at low throttle openings and a broader power band at higher engine speeds. The long tube design not only supports peak horsepower gains but also smooths response during part-throttle operation, resulting in enhanced drivability for street or strip use.
Advanced Ceramic Coat for Thermal Control
Each header tube and merge collector receives a durable ceramic layer that reflects radiant heat back into the exhaust stream. By retaining thermal energy inside the pipes, this coating accelerates gas flow and improves scavenging effects, yielding crisper throttle response and marginal horsepower gains. Underhood temperatures are also significantly reduced, protecting nearby components such as wiring looms, intake plenums, and fuel lines. The ceramic surface resists impact damage and resists flaking even under repeated thermal cycling. This level of heat management is critical for sustained performance, ensuring that the exhaust system maintains consistent output during long runs or back-to-back dyno sessions.
Precision Fit and Swap Support for X-Body
Thick 0.375 inch CNC-formed flanges provide a perfectly flat sealing surface, eliminating exhaust leaks and ensuring a reliable long-term seal against the LT cylinder head. All joints are assembled with high-quality MIG welds in mild steel that withstand continuous expansion and contraction without cracking. Designed specifically for the 1975–1979 X-Body chassis, these headers align precisely with MuscleRods mounts, guaranteeing correct engine placement and ideal driveshaft angles when performing an LT engine swap. This factory-style fitment reduces installation time and prevents common clearance issues around steering components and front suspension members. The result is a robust, ready-to-run package that delivers both reliability and performance for any LT-powered X-Body project.
Trust in the precision fit and ceramic heat control of these LT headers to provide reliable performance for your swap into a 1975-1979 X Body chassis.
