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 and Stan’s Headers. Hooker uses the 4-into-1 design with long transition collectors for reduced back pressure and increased flow. The Stan’s Tri-Y headers are the best fitting Tri-Y’s we’ve ever found. They offer nice spark plug clearance on small bolt-pattern heads with the 351W plug placement and provide an excellent overall fit. Optional silver ceramic high-temp coating inside & out is available, and we can also apply an additional “period correct” looking flat black top coating. Street/Strip headers will work with mechanical clutch linkages.
