Overall Assessment

Customers appreciate the quality of our product, noting that it fits perfectly and can be used for a variety of applications like dirt track modified. Though useful for those with fabrication skills, certain components might need additional purchase to accommodate specific models like a small block Windsor. Despite this, users mention it remains more economical than the competition. Overall, it's recommended for its high usability and excellent value.

Had to buy a flange kit and header gaskets for a Ford because Speedway does not make it for a Small blosk Windsor. It did not come with header bolts.

I actually used this kit to build some headers for a small block Mopar. I had to buy 4 180 deg pipes and flanges to make it fit how I wanted. Still way cheaper and easier than buying a box of bends!

Would Recommend

I would buy this kit again if I ever need another set
