Details

These tight-fit headers are designed to be used with standard exhaust port Small Block Chevy heads that have angle spark plugs. Features 1-5/8" primary tubes and 2-1/2" collectors with 2-1/4" outlets. Comes with bolts, gaskets and reducers. The port openings on the header are round and work fine on heads with round or rectangle ports.

These shorty headers feature our unique AHC ceramic coating. Armor Hot Coating (AHC) is a heat resistant, ceramic coating applied to the outside of the header. This coating will reflect heat, which helps retain more heat within the header tube while simultaneously speeding up the exhaust flow. Not only will this coating help you make more horsepower, it also keeps your headers rust-free, looking great, and lasting longer (when properly maintained). If you are looking for a show-quality finish for your headers, this is it! Our AHC ceramic coated headers will withstand exhaust temperatures of up to 1300° F.

Application

  1. Can be used with most oil filter systems and transmission/starter combinations.
  2. Does not fit '55-'57 Chevy cars, Camaros, or other modern vehicles which have a crossmember below the engine's center two exhaust ports.

Warranties

AHC Warning: AHC coatings will burn and be damaged at exhaust temperatures over 1300 degrees. A lean fuel mixture can generate exhaust temperatures exceeding 1700-1900 degrees. If the coating is damaged due to a lean condition, the coating will not be warranted, but can be recoated for a fee.
