    To finish off a clean and well-protected Exhaust Insulating Wrap application it is recommended to use the Hi-Heat Coating. The coating will protect the wrap from abrasion and harmful liquid spills. Extra resins and binders toughen the surface, extend the life of wrap by protecting it from friction, and seal the pores to minimize the penetration of harmful liquids.

    The coating also works excellent as a paint directy on metal surfaces.

    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.
