This is one of the reasons with having multiple race cars, especially with a few under construction. Not enough hours in a day to get all 100% perfect. I usually concentrate on 1 at a time and headers on AH car are far from where I want them right now. But they work. I may do that in future but I still dont think I would want that design copied. Custom fit and tube sizes reduced. Older technology should sometimes be left in the past. And that car is setup for eliminator and not shoot out. Right now feeding one of the other rides that I shouldve never shelved while looking for a 200 mph fix!

If you have more than one set of headers that need to be made or other racers that need some flying him in if he still does that maybe the solution. When RJ and i were building a late model CJ we flue him in to San Antonio TX and he built 2 sets of stepped headers in a day and one half. One for us and one with a different tube location because they used a different firing order on another CJ project. The only thing we supplied was a tig welder and he shipped all the needed tubing for the job. Watching Greg work was unbelievable. He even made some jigs for the headers. He talked us out of stainless headers.

Do the NASCAR teams build their own headers?

What makes ACP, Kromer Kraft and Precision Welding headers special.

Does anyone use Kooks Headers?

KromerKraft located in Youngstown, OH can do mild steel with ceramic coating, stainless steel or titanium,....but mild steel + ceramic coating is typically recommended.

Each have their own formulas for tube diameter, length to each step, Step change in diameter, collector size. Overall design of header 4 into 1 or Tri-Y. These factors will determine how hard they suck exhaust out the port, control reversion pulses not allow them to make it back to the valve stalling flow. Controlling signal getting back to the carb effecting fueling. Build quality placing bends and their radius.

Not saying a custom set will "always" outperform a set of box headers.
Depends on the combination.
A box header can be optimal.
Improvement can be minimal.

Improvement can also be impressive.

There are old threads on Speed Talk with comments by Calvin Elston and others which if your interested in understanding theory behind header design are very informative. Search "Exhausted".

I usually scrub my headers with a brush and a bucket of soapy water then rinse with a hose. Use a long tapered brush meant for cleaning under refrigerator or heating unit. It looks like and anteater. Lot's of junk will be in the bucket.

Fog your engine good when done for the weekend and plug collectors with rags. Replace your good race plugs with a set you only use for fogging and warm up after sitting a few weeks.
