78-87 Buick V6 Regal

The 78-87 Buick V6 Regal headers from HEDMAN are designed for automotive enthusiasts looking to enhance the performance of GM 3.8L or smaller V6 engines found in second-generation Regals. These headers effectively address the limitations of stock exhaust manifolds, which often feature restrictive port designs and unequal runner lengths.

Constructed from mandrel-bent steel tubes, these headers feature stepped primary runners with diameters ranging from 1.5" to 1.625". This design optimizes exhaust velocity and improves scavenging, which is crucial for maintaining low-end torque in smaller-displacement engines. The headers also come with ceramic or metallic coating options that resist thermal stress and corrosion, ensuring durability in classic Buick applications.

Ideal for both weekend cruisers and restoration projects, these headers are compatible with 1978–1987 Buick V6 Regals. Upgrading from cast iron manifolds to these quality headers is one of the most effective modifications for naturally aspirated V6 platforms, providing significant performance gains while maintaining a compact design for engine bay clearance.
