Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP head studs are popular among leading Sport Compact/Import racers.You should know that ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. Following heattreat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It's important to note that lesser quality studs are not even centerless ground the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that won't happen with inferior quality head studs.ARP studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat.You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force one that compensates for head gasket compression when the head is installed. This helps prevent blown head gaskets, and assures optimum sealing!

These studs threaded in perfectly. I did thread chase every one of them. The quality was impressive and I could tell they torqued proper as well.

seem to be working so far. They say not to retorque them. I am going to contact them to see if I can check the torque at least. I am just use to torquing them a bit more after a thousand miles or so.

Best head studs in the industry. I have installed several sets of ARP studs on different vehicles over the years. The added clamping force and high quality alloys prevent any further issues with head gasket leaks or bolt stretch in extreme power producing engines. Building a reliable, high power engine is easier with ARP.

Very pleased. name brand ARP studs at a good price. I used them on 2 Dodge 12 Diesel Engines when I changed the head gaskets.

Nothing wrong with product. Paid extra for shipping and then ups nailed me close to fifty bucks to get it over the border. A very expensive set of bolts was almost a hundred dollars more than advertised
