The Stainless Works long tube headers for 1968–1972 big block Chevelle, El Camino and Monte Carlo use 1‑7/8" primaries with 3‑1/2" slip‑fit collectors to support strong torque and street performance. Built from 304 stainless steel with CNC mandrel bends and CNC laser‑cut flanges, they are finished in mill form. The design may require a mini‑starter for clearance; headers ship with bolts and high‑temp RTV, are TIG welded, and include a lifetime warranty.
