If you're diving into some serious engine work, you might want to check out the ARP Buick 455 12Pt Head Stud Kit. Trust me, these aren't just any fasteners; they’re crafted from 8740 chromoly, which means they’re built to handle the kind of stress that comes with high-performance applications. You don’t want to skimp on quality when you’re dealing with the heart of your ride.
The head studs feature a 12-point design, making them easier to work with in tight spaces. No more fumbling around with a standard hex; these studs give you a solid grip, which is a game-changer when you're cranking down that torque. And yeah, they come with washers, so you’ve got everything you need right out of the box. Just one less thing to worry about when you're in the thick of it.
One thing I appreciate is that these studs don’t have an undercut, which adds to their strength and reliability. You want your engine to perform at its best, and using quality fasteners is a big part of that. Plus, the black oxide finish not only looks slick but also offers some added corrosion resistance. It’s a little detail that goes a long way in keeping your build looking sharp and lasting longer.
Just a heads-up: these are cut to fit, so you won’t have to mess around with any modifications. It’s all about getting your Buick 455 set up right the first time. Whether you’re going for a full rebuild or just sprucing things up, this head stud kit is a solid investment for anyone serious about performance.

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.
