Importance of Exhaust Headers Headers are one of the easiest bolt-on accessories you can use to improve an engine's performance. The goal of headers is to make it easier for the engine to push exhaust gases out of the cylinders. When you look at the four-stroke cycle in How Car Engines Work, you can see that the engine produces all of its power during the power stroke. The gasoline in the cylinder burns and expands during this stroke, generating power. The other three strokes are necessary evils required to make the power stroke possible. If these three strokes consume power, they are a drain on the engine.

Product introduction

Shipping Notices

The exhaust manifolds found in the 1955-1957 small block Tri-5 Chevy engines were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 block hugger 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. Block hugger style Headers are meant to be used where space for long tube Headers isn? T available due to steering and cross member clearance issues. Tubing has been optimized for the 265 and 283 engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
