What's in the Box

Info

If you are lucky enough to have a GM small block crate motor with D-port heads (FastBurn, ZZ4, etc.) you will find that regular headers just don't work. These shorty headers were specifically designed for these heads. These tight-fit headers are ceramic coated headers that feature 1-5/8" primary tubes and 2-1/2" collectors with 2" reducers. Includes bolts and gaskets. The block hugger headers are designed to make difficult installations easy.

  • Collector exits parallel with the oil pan rail for maximum ground clearance
  • Made from lightweight & sturdy 18 gauge tubing
  • Tight-tuck design for narrow frame rails

Notes

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 will withstand exhaust temperatures of up to 1300¢ª F. 

Warranties

Warning: AHC coatings will burn and be damaged at exhaust temperatures above 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.
