The 88-90 Small Block Chevy Pickup headers by HEDMAN are essential exhaust headers designed for serious small-block engine builds in classic Chevrolet trucks from 1988 to 1990. These headers replace restrictive factory castings, significantly enhancing horsepower, torque delivery, and throttle response. Whether you're restoring a C10 for improved performance or building a high-output vehicle, these headers are a crucial upgrade.
Constructed from high-temperature steel with full welds and port-matched flanges, HEDMAN headers are engineered to withstand sustained heat cycles without warping or cracking. The mandrel-bent primary tubes optimize scavenging and exhaust gas velocity, particularly in the 5,000–7,000 rpm powerband typical of small-block trucks. The tuned tube lengths are designed to match cylinder firing order and displacement characteristics, ensuring balanced exhaust pulses and reducing reversion.
These headers are ideal for builders looking to maximize performance in their Chevy small-block pickups. Installation is straightforward for anyone with basic mechanical skills and a quality torque wrench, as factory bolt holes align directly with existing engine bay mounting points. Whether for daily driving or weekend racing, these headers provide reliable performance enhancements.
