Q & A

What's in the Box

These small-block Chevy 265-400 V8 headers are designed for optimum performance in a variety of 1935-1948 fat-fendered street rod and pickup applications. Perfect for Gasser-style rods and drag cars, the ceramic coated headers have long primary tubes that curve over the frame and through the fender wells. You must cut the inner fender panels to make them fit. These fender well, ceramic coated headers provide superior performance and durability.

Includes collectors, collector gaskets, header gaskets, header bolts, and collector bolts.

Application

  1. Can be used with most oil filter system or transmission and starter combination.
  2. Fits most angle plug heads.
  3. Check motor mount position before ordering.
  4. Not legal for sale or use in California on pollution controlled vehicles.

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° F. 

 

Warranties

AHC coated headers will burn and be damaged at exhaust temperatures above 1300 degrees. An excessively lean fuel mixture can generate exhaust temperatures over 1700-1900 degrees. If the coating is burned (which will look like a dull gray) due to a lean condition, it is not warrantied, but the headers can be recoated.

are you sure these were'nt custom made j

March 10, 2014
my 41 ford coupe use to be a race car back in the 60's and apparently it was on a tight budget, it already had fender well headers on it that were home made and leaked like bad toilet plumbing. The car was already lifted about 3" all around but now its time to step it up so I have put a new 383 stoker in and raised the front end 3" more and now new fender well headers to give it that full gasser look and I couldn't be more happy, they fit like they were custom made for my car #not like the old ones# and now my car has that bad*** look. thanks I love my new headers and the AHC coating looks great and the fit.....the fit is fantastic. thanks again

Nice Fit Poor Quality On AFC Coating

September 04, 2011
The fit is very nice in my 35 Ford, but save your money on the coating. The coating is uneven, thin, scratches easily and is discoloring just after start up. A can of paint would look and last just as good. The header itself is a good Product
Pros:
  • Easy To Install

I am about to buy new SBC AFR 195 heads, and plan on running these headers. Would they fit better on a angle plug or straight plug head? Thanks!

These small block chevy fenderwell headers fit most angle plug heads. Base of flange to bottom of collector is 9" At approximately 6" from flange at 2nd bend, there is about 2" of drop from flange. At approximately 15" from flange at 3rd bend, there is about 4" of drop.

Yes, they will. If the bolt hole center to center dimension is 4.00" at your middle exhaust ports, most headers with a standard Chevy flange will work.

I plan to install these headers on a 1950 chevy delivery sedan. Are there any issues that I might not be aware of in the install? (ie: steering shaft clearances,) I plan to use a rack & pinion steering system especially for straight axle applications.

Part number 9300150H Depending on engine location and steering shaft location there are many variables. From a visual at the photo and the dimensions that follow some basic measuring should help determine fit. "A"...19" From head surface out to furthest point "B"...11 1/4" From top of flange to lowest point at the collector "C"...27" From front of flange to end of the collector. At approximately 6" from flange at 2nd bend, there is about 2" of drop from flange. At approximately 15" from flange at 3rd bend, there is about 4" of drop from flange
