Schoenfeld Street Stock Headers
Get conventional for your Circle Track Street Stock with Schoenfeld headers. Their steel Street Stock headers offer bolt-on performance and a great price. Schoenfeld specializes in competition products, and their headers are available in dozens of configurations, flange styles, and tube diameters. Make some power to perform; order the headers recommended for your vehicle.
(Special warning regarding Schoenfeld painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.)
