Polished Stainless Steel Long Tube Headers – Fits 1973–1991 Classic Chevy/GMC TrucksUpgrade your classic Chevy or GMC truck with these polished stainless steel long tube headers, engineered for Small Block Chevy engines. Compatible with Gen 1 SBC motors ranging from 265 to 400 cubic inches, these headers are ideal for owners restoring or modifying 1973–1991 C/K Series pickups, K5 Blazer, Suburban, Jimmy, and other Square Body models.
These headers are compatible with both two-wheel and four-wheel drive configurations. On stock-height 4WD trucks, slight trimming of two front leaf spring bolts may be necessary for proper collector clearance. Lifted 4x4 trucks generally provide adequate space without modification.
For best results, use compact “header-style” spark plugs and plug wire heat protection. Standard spark plugs may present clearance challenges during installation.
Compatible with Small Block Chevy V8s including 265, 262, 283, 305, 307, 327, 350, and 400ci engines (1955–1995) when installed in 1973–1991 trucks.
