Barn Fresh
Building a vintage hot rod wrapped around a modern chassis and body is a popular segment of the hobby today. Over 10 years of parts collecting went into the construction of this hot rod. The finishes on this car all look 50 years old, but in reality, the car has only been built for 5 years. It is a masterful blend of the old and the new.

FROM RAW TO REALITY
In the midst of all the wait comes this brand-new and, dare we say, quite revolutionary roadster/convertible, and a whole new wave of “…there’s not a chance.” Opinions surfaced. We took the high ground, as we have sat and listened intently to the plans for HRH, have visited facilities where some of the early work had been done, and are of the opinion that what the company has set out to do is not much different than any of us, only HRH bit off a whole mouthful.

If you live for pulling trucks, racing, or high-performance applications, this build kit has everything you need to bring your vision to life. It’s designed to fit the standard bore space of big block Chevy heads, making it versatile enough for a variety of builds.
Unparalleled Precision and Quality
What sets this header build kit apart from the rest? It’s all about the details:
- Flanges: The kit includes two American-made, precision laser-cut 3/8″ thick header flanges specifically designed for Big Block Chevy heads. You can also opt for eight single port flanges for easier fabrication and installation.
- Full Bank Port Size Options: Choose from 2″, 2 1/8″, 2 1/4″, 2 3/8″, or 2 1/2″. Single port flange options are available in 2 1/4″, 2 3/8″, or 2 1/2″.
- Mandrel Bends: You get twelve 180-degree J bends with 6″ and 12″ legs. These extra-long legs mean you won’t need to buy additional straight tubing. The bends are crafted from American-made 304 stainless steel, which forms better, welds better, and lasts longer.
- 4 into 1 Collectors: The kit offers precision-formed 4 into 1 collectors or optional super high-flow slip-on merge collectors with four sets of collector tabs. Like the bends, these collectors are made from top-quality American-made 304 stainless steel.
- Collector Stars: These laser-cut stars simplify the fabrication process, acting as a weld-in block between the tubes before attaching the collector.
- Purge Caps: Back purging is a breeze with these caps. Each kit includes four primary caps and one collector cap.
- O2 Bungs: Two precision-machined, weld-on O2 bungs are included. Made from 304 stainless billet, they weld beautifully.
- Tig Filler Rod: The kit includes a half-pound package of filler rod, ensuring you have everything you need for a perfect weld.
