POCKET ROCKET
The very concept of a V-8-powered Ford Focus isn’t as new as it is novel. In fact, we introduced Jerry Kugel’s install kit some years ago and then followed it up with the mod-motor install. But that was then, and now ASE master technician Donny Seyfer, from Wheatridge, Colorado’s Seyfer Automotive, decided to tackle the building of such a hybrid.

PRODUCT SPOTLIGHT: DeatschWerks Performance In-Tank Regulators
In the realm of high-performance automotive engineering, fuel flow reigns supreme as the lifeblood of optimal power delivery. DeatschWerks emerges as a game-changer with their Performance In-Tank Regulators, engineered to unleash the true potential of EFI engines.

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.
