The CAE-045 Big Block Chevy turbo headers are precision-built components engineered for custom fabrication and vintage engine projects. Constructed from polished 304 stainless steel, each header uses 2.25-inch primary tubes and a 3.5-inch V-Band outlet in a compact, forward-facing configuration that supports twin-turbo or custom plumbing layouts. Every assembly features TIG-welded seams, CNC-cut 5/16-inch flanges, and mandrel-formed tubing for consistent alignment and dependable strength under high-temperature conditions. The polished stainless finish provides corrosion resistance and a clean, professional appearance. Each set includes a left and right header, matching 3.5-inch V-Band flanges, clamps, and installation hardware. Designed to fit Big Block Chevy engines including 396, 402, 427, 454, 502, and 572 cubic-inch configurations, these headers offer adaptable geometry for a range of custom builds. Intended for use in custom projects, vehicles manufactured in 1967 or earlier, and non-automotive engine applications. Verify dimensions and clearances before fabrication or installation.
