On a boosted 2JZ they're the part that stops the head lifting when cylinder pressure climbs past what factory bolts were designed for.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe manufacturing is the reason for the price.\u003c\/strong\u003e ARP uses premium grade 8740 alloy rated far superior to \"aircraft\" quality, with each stud placed vertically in special racks and precisely heat-treated to 200,000 psi — that ensures complete heat penetration rather than dumping pieces in a basket and hoping.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAfter heat treat, each stud is centerless ground through about ten very slight cuts to make it as close to perfectly concentric as possible. The practical result: gaskets and cylinder heads literally glide into position and align perfectly, which doesn't happen with inferior studs.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThreads are rolled after heat treat\u003c\/strong\u003e, giving roughly 1000% better fatigue strength than studs threaded before heat treat — a very common industry practice elsewhere. It costs more and it's hard on tooling, and it's why these hold.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eStud ends are broached for easy installation, which also lets the cylinder head come off in tight quarters — worth something on a Supra with the engine in the car.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIncludes heat-treated chrome-moly 12-point nuts and parallel-ground washers for even load distribution and accurate torque readings.
