BBC Headers 1-7/8 Dia. Coated

The Doug's Headers Big Block Chevy Headers with 1-7/8 inch diameter primary tubes deliver proven performance for classic muscle car restorations and high-output engine builds. Designed specifically for GM F-Body applications from 1970 to 1981, this full-length header set maximizes exhaust scavenging and flow characteristics that factory manifolds simply cannot match. The ceramic coated steel construction protects against thermal degradation while maintaining the structural integrity required for sustained high-RPM operation.

Each pair features 1-7/8 inch primary tubes that merge into a 3.5 inch collector, a proven configuration for big block Chevy engines seeking optimal header scavenging across the RPM range. The 1-7/8 diameter primary sizing balances velocity retention in mid-range operation with adequate cross-sectional area for peak power at elevated RPM. Gaskets and hardware are included, eliminating the need for sourcing fasteners separately. The ceramic coating resists corrosion and heat discoloration, extending service life in both street and track environments where engine bay temperatures reach extreme levels.

These headers serve restoration shops, hot rodders, and performance enthusiasts rebuilding second-generation F-Body Camaros, Firebirds, and Transams with big block power plants. Serious builders choose Doug's Headers when maximizing exhaust efficiency is non-negotiable. The full-length design preserves proper header tube length for scavenging dynamics that bolt-on replacements often compromise. Weighing 48.8 pounds for the pair, installation requires adequate engine bay clearance and header-specific exhaust plumbing downstream of the collectors.
