Q & A

What's in the Box

Rodders and racers are known for wedging big engines into small spaces, so these big-block Chevy shorty headers are designed for applications where space is limited. They offer great flow in a compact package and will fit where many other headers won’t. These block hugger headers make difficult installations easy. These shorty headers are ceramic coated headers.

  • Fits round-port cylinder heads
  • Compact design fits a wide variety of applications
  • Made from 16-gauge tubing
  • Includes reducers, gaskets, and bolts
  • 1-3/4” primary tube diameter
  • 2-1/2” collector diameter
  • Can be used with most oil filter systems and transmission/starter combinations
  • Will not fit '55-'57 Chevy cars, Camaros, or other modern vehicles which have a crossmember below the engine's center two exhaust ports
  • Fits standard deck big blocks only

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.

NOTE: Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperature. Please note that the finish of the header when the engine is started, will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished back out when utilizing Blue-away or Simi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.

Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.
