Replacing the stock bolts with studs helps keep the head gasket sealed when the engine is running with higher turbo pressure or higher compression.\u003c\/p\u003e\u003cp\u003eThey are manufactured from ARP2000, a proprietary ARP alloy that reaches a tensile strength of about 220,000 psi and maintains its properties better than chrome-moly at high temperatures. Each stud is centerless ground after heat treatment to ensure it is perfectly concentric, allowing the gasket and cylinder head to seat in alignment, and the threads are rolled after heat treatment, which ARP states increases fatigue strength by twenty times.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their specified torque values, as the load on each part will differ with other lubricants.
