The 68-87 BBC Truck Headers by Hedman are high-performance exhaust manifolds designed specifically for big block Chevy (BBC) engines in full-size trucks and SUVs from 1967 to 1991. These headers are ideal for mechanics and automotive enthusiasts looking to enhance their vehicle's performance by replacing restrictive factory cast-iron manifolds.
Constructed from mandrel-bent steel tubing and finished with a black powder coat, the headers feature 2-inch primary tubes that merge into a 3-inch collector. This design optimizes exhaust flow and scavenging, improving engine breathing and performance across the RPM range. The stepped primary design also accommodates the tight engine bay clearances typical in truck applications.
Owners of 396, 427, or 454 big block engines will experience noticeable improvements in throttle response and peak power. Each set includes gaskets and mounting hardware for a straightforward installation, making these headers a practical upgrade for anyone restoring or modernizing a classic Chevy truck or SUV.
