Hedman Hedders 69130 Long Tube Headers Big Block Chevy 2WD Truck

The Hedman Hedders 69130 are long tube one-piece headers constructed from mandrel-bent 16-gauge steel with 2-inch primary tubes designed for big block Chevy engines (396, 402, 454, and 502 ci) in 1967-1991 Chevrolet and GMC 2WD trucks, Blazers, Suburbans, and Jimmys. These headers deliver horsepower and fuel economy improvements while being guaranteed free from defects including cracks in tubes and welds for the life of the headers.

Key Specifications:

• 2-inch primary tube diameter
• 3-inch collector diameter with ball and socket flange attachment
• Collector reducers included (2.5-inch exit diameter)
• 16-gauge steel construction with 0.31-inch flange thickness
• Sold as a pair with gaskets, bolts, and mounting hardware included

Important Installation Notes:

• Designed for vehicles without smog injection or injection heads
• Requires factory big block Chevy hardware and mounts
• Does not fit vehicles with offset (right) engine position
• Temporary paint coating will burn off during use; high temperature coating recommended

Each set uses CNC mandrel-bent tubes that are hand-welded for consistency, featuring a gasketless ball and socket collector design that allows the exhaust system to bolt up even if not perfectly aligned. The long tube design maximizes exhaust flow for improved midrange and top-end horsepower while reducing backpressure.
