Q & A

What's in the Box

These long tube headers work with both automatic or manual transmissions in 1964-1989 Chevrolet chassis. Features 1-5/8" primary tubes, 3" collectors, and fits angled or straight plug S/B Chevy oval exhaust port heads. Built with surface machined thick steel flanges for a great seal and mandrel bent mild steel tubing. These headers are a chassis header and are meant to go inside of the frame rails on the 1965-1989 Chevrolet chassis.

Available with metallic ceramic coating. Unlike paint or chrome, metallic ceramic coating is easy to keep clean, resists rust and corrosion and will not discolor. Metallic ceramic coating also reduces underhood temperatures.

Headers come with installation hardware, collector reducers, gaskets and instructions.

Item Details

AHC Coated

Application

Applications include, but not limited to:

  • 1965-1989 Impala, Caprice, Bel Air, Biscayne
  • 1967-1981 Camaro (except 1967-69 with factory A/C)
  • 1964-1987 Chevelle, Malibu, El Camino
  • 1970-1987 Monte Carlo
  • 1968-1979 Nova

Notes

  1. Fits D-Port cylinder heads including ZZ4 crate engines
  2. Does not fit 67-69 Camaro with A/C
  3. Will fit most angle plug heads including factory Chevrolet “Bow-Tie” heads
  4. Requires removal or modification of locking steering columns if equipped
  5. Installation requires left side A/C bracket; later vehicles with short compressors can use the stock bracket
  6. Will fit Detroit Speed & Engineering front subframes with rack and pinion steering
  7. These headers are a chassis header and are meant to go inside of the frame rails on the 1965-1989 Chevrolet chassis.

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 1300Ëš F.

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.

Nice looking set

February 08, 2013
I contacted the service dept. with a question on these headers and it was suggested that I use these for added ground clearance.I needed them for a truck and these were for a car. It also said some modifications may be needed. They were right as nothing fit in the compartment of my truck. Well I made the changes needed and YES they give excellent ground clearance after redesigning the motor mounts and some welding. Not a good idea if you don't have the expertise, knowledge and equipment to make the needed modifications. Yes I am impressed with the fit and especially the added ground clearance as my truck is slammed to the ground. Thanks for the great advise and warning SOME MODIFICATION WILL BE NEEDED.
Pros:
  • love the hidden look
  • perfect fit now
  • expert advise from you guys.
Cons:
  • lot's of extra work for the different application.
Yes, I recommend this product.

Awesome headers

April 03, 2012
My old headers hung down and would drag over my curb into my driveway, these are tucked up close and the collectors are rounded, so I don't think I will have that problem anymore. I had a hard time finding headers to fit with my 350 manual transmission and power steering - these were perfect and look nice too!
Pros:
  • Hugs close
  • Looks good
  • Fit perfectly
Yes, I recommend this product.

Using header number 9300110H on a 67 Impala with dropped spindles and air ride will likely limit your driving to very smooth surfaces because of lack of ground clearance and when air bags are deflated the headers will likely be on the ground before the frame rails. For your configuration the Mid Length headers would be suggested under part number 9300109H.

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.
