  • Tubing Thickness:  12 gauge (.103")
  • Header Flange Thickness:  0.30"
  • Exhaust Flange Thickness:  0.3760"

Header Dimensions (GIF) 

Fits 283-400 S/B Chevy V8s with straight plug heads.

Note: Will not fit 168 tooth flywheels or kickout aftermarket starters. Will not fit manual transmission cars with factory Z bar clutch linkage.

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.

Specs


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.

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.

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.
