On a built SR20 that's the whole job — head lift is what kills gaskets, and no gasket fixes a fastener problem.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eManufactured from premium grade 8740 alloy\u003c\/strong\u003e heat treated to 200,000 psi. Each stud is placed vertically in special racks during treatment, which ensures complete heat penetration rather than dumping pieces in a basket and hoping for the best.\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 result is an exceptionally straight part — heads and gaskets glide into position instead of fighting you during assembly.\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, which is common practice elsewhere. Pro Series studs are also cold-forged to preserve molecular integrity.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e M11 x 1.5 thread, 12-point nuts, 8740 chromoly, black oxide, undercut.
