Fit 67-72 396/402/427/454 V8 Chevy Big Block Long Tube Header Exhaust Manifold. Our 4-1 Long Tube off-road headers are designed to allow the exhaust gasses to flow more freely from each cylinder bank and combine in a more efficient manner.

These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound. Made of high quality T-304 stainless steel material.
