If you're diving into a build with a Chevy Big Block MKIV, especially if you're working with those Merlin heads, you’ll want to take a good look at the ARP 235-4325 Exhaust Stud Kit. This isn’t just any kit; it’s designed to handle the heat and pressure that comes with serious horsepower. Trust me, I’ve been there, and having the right fasteners makes all the difference.
First off, these studs are made from chromoly—a material that’s tough as nails. You’re not just getting any run-of-the-mill fasteners here. The black oxide finish adds a layer of protection against rust and wear, so you know they’ll hold up over time, even in the roughest conditions. And let’s be real, if you’re pushing your engine hard, you want to make sure everything stays put.
Now, about the 12-point head style; it’s not just for looks. The design gives you a better grip when you’re tightening things down, which is crucial when you’re working in tight spaces or dealing with high torque. Plus, this kit includes washers, which is a nice touch. They help distribute the load evenly, so you don’t have to worry about warping or uneven stress on the heads.
One thing to note is that these studs are not cut to fit, so make sure you’re ready to install them as-is. But if you’re looking for reliability and strength, this kit has got you covered. I’ve used similar setups in my own builds, and I can tell you that having solid fasteners is half the battle won.
In short, if you want a dependable exhaust stud kit that’s built to last and can handle the demands of a high-performance engine, the ARP 235-4325 is definitely worth considering. You’ll appreciate the quality and peace of mind it brings to your project.

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.
