For Big Block Chevy enthusiasts requiring a slightly longer fastener, this Auto Racing Products header bolt kit is the perfect solution. Featuring a 1.00-inch under-head length, these bolts provide the necessary reach for thicker header flanges or applications using additional spacers. The 12-point head design ensures that you can achieve proper torque specs even in tight, crowded engine bays, while the polished stainless steel material offers unmatched durability and a clean, professional aesthetic.

Technical Specifications

  • Thread Size: 3/8-16
  • Under Head Length (UHL): 1.00 inch
  • Head Style: 12-Point
  • Material: Polished Stainless Steel
  • Quantity: Set of 16 bolts
  • Application: Big Block Chevy

These bolts are specifically engineered to handle the high vibration and extreme heat associated with high-output Big Block Chevy engines. By utilizing high-tensile stainless steel, these fasteners resist the stretching and loosening that can lead to exhaust leaks and power loss. The polished finish is not only visually appealing but also provides a layer of protection against the elements. If you are looking for reliable, high-performance hardware that stands up to the rigors of the track or the street, this kit is an essential upgrade for your build.
