If you're diving into the world of Porsche performance, you know that every detail matters. That's why I want to share my experience with the ARP Porsche 911-930 Turbo SS Head Stud Kit. This isn't just another set of fasteners; it's a game changer for anyone looking to get the most out of their ride.
First off, let’s talk about the fastener style. We’re dealing with a stud design here, which means you get a solid grip and reliable clamping force. No undercut stud nonsense either—this is straightforward and robust. The 12-point head style makes it easier to work in tighter spaces, which is a blessing when you're knee-deep in a project.
Now, the material is where things get really interesting. These studs are made from 8740 chromoly, which is known for its strength and durability. This stuff can handle the heat and pressure that comes with high-performance engines, making it perfect for those who like to push their Porsches to the limit. And with a black oxide finish, not only do they look slick, but they also resist corrosion, so you won’t have to worry about them rusting out on you.
And yes, they come with washers included, so you won’t have to scramble to find the right ones when you’re ready to install. Just keep in mind that these are cut to fit, so you’ll want to make sure you’ve got the right setup for your specific model.
Speaking of fitment, this kit is compatible with a range of classic and modern Porsches, including:
So, if you're looking to enhance your engine's reliability and performance, this head stud kit is a solid investment. I’ve seen firsthand how it can elevate your build, and I can’t recommend it enough for anyone serious about their Porsche.

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.
