    Note: The exhaust port size is square and large enough for most round port heads. It measures 1.375" x 1.375" and should be sufficient for most small block cylinder heads. Variation in location of spark plugs on aftermarket heads makes it impossible to verify that the Tru-Ram® will fit all heads on the market, but it will clear most straight and angle plug heads.

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.

    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.
