Speedway Motors 930CER100H Details

Modeled after headers used on sprint cars and other open-wheel racers, these small-block Chevy Sprint Roadster headers have an aggressive style that makes them our most popular headers for T roadsters. Designed for early street rods without hood sides. They route the exhaust over and outside the frame rail, along the side of the car. These ceramic coated headers provide superior performance and durability.

  • Fits standard or Vortec head Small Block Chevy (not D-port style heads)
  • Fits most angle plug heads
  • Extensions and mufflers are sold separately

Item Details

Armor Hot Coat® (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.

Charts

Warranty Information

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.

was hoping these were the ones

Bought these for my27 T roadster , This was the 3rd set I have tried and have all been failures although only one set was speedways , They looked great when I got them an thought I finally got it right , After starting and letting it run for a while all looked great , after about the 4th startup I noticed a burnt spot on the finish of #8 cylinder about 2" out from the flange and about 3-4" long so I checked it with laser temp tester and all cylinders were 275-325 in temp except #8 and it was running about 625-650 , Wasn't sure what was causing the problem so checked valve lash and for vacuum leaks and timing could find nothing wrong so removed the header and found a flaw in the weld area I was not sure if it was deflecting the flow to the side of the tube and burnt it, Was confirmed when I put the old chrome sprint header back on and had no more hot spot.

They are a little disappointing. The quality of the finish isn't very good. I really wanted stainless steel headers in the roadster shape.

The finish on these is for the most part pretty good however there are a couple flaws but nothing major. What I like the most is the thick and flat flange which will make for a very good seal. I only have about 60 miles on these so far so I don't know how well they'll hold up but I would buy them again.

Love the look
