If you're diving into a Datsun A-14 build, you’re going to want to check out the ARP 202-4203 12pt Head Stud Kit. This isn't just another set of fasteners; these are serious pieces of engineering designed for those who know what they're doing under the hood.
First off, let's talk about the fastener style. We’re looking at a stud design here, which means you get a more secure fit when it comes to your cylinder head. No undercut studs to worry about, just solid performance. The head style is a 12-point, which not only looks sharp but also makes it easier to get a good grip when you’re tightening things down. That’s a big plus when you’re working in tight spaces.
Now, the material is where things get really interesting. These studs are made from 8740 chromoly, a high-strength steel that can handle the heat and pressure of performance engines without breaking a sweat. You’ll appreciate that durability when you’re pushing your Datsun to its limits. Plus, they come with a black oxide finish, which not only looks slick but also adds a layer of corrosion resistance. Trust me, that’s something you want in your engine bay.
And yes, they come with washers included, so you won’t have to scramble to find the right ones when you’re in the middle of your project. Just remember, these are cut to fit fasteners, so make sure they work with your setup. But once they’re in, you can expect a solid seal that’ll keep everything running smoothly.
In short, if you’re serious about your Datsun A-14, this head stud kit is a no-brainer. It’s built for performance and reliability, and you can feel good knowing you’ve got quality fasteners holding your engine together.

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless.
Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.
What Makes ARP Bolts So Special?Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes.
ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.
ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
