Internal combustion engines are big air pumps; volumetric and thermal efficiency are keys to power and reliability. For street/strip applications we offer headers from Hooker. Hooker uses the 4-into-1 design with long transition collectors for reduced back pressure and increased flow. Optional silver ceramic high-temp coating inside & out is available, and we can also apply an additional “period correct” looking flat black top coating. These headers will work with mechanical clutch linkages.
