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!

Not sure what these fit, but it’s not a 94 Del Sol SI. With a D16Z6, they were entirely too long. Save your $

I think the sheet called for 80ft lbs for a B18, which is a crazy generic number likely based on a steel block. Further research shows 65lbs to be adequate and still scary tight.

Used with a Cometic head gasket on a B20Z2 and they worked out wonderfully! 6 months on the motor and I'm VERY pleased.

These are a must have if having to replace or fix the head, they are well worth the money and make the job that much easier.

They're holding up so far, at about 400 miles in a stock B18B1 swap. I wouldn't expect any less from ARP.
