1. To ensure proper thread engagement and accurate torque readings, clean all threads in the block. Chase if necessary with ARP Thread Chaser.
2. Clean the spot faces on the cylinder head where the washer seats, use of solvent or brake/carb cleaner is recommended.
3. Install the head gasket and cylinder head.
4. Screw the studs into the block hand tight, do not apply torque. The hex broach in the end of the stud is designed to assist with installing/removing the studs from the block, not for applying torque.
5. Then, using a clean, dry rag remove all oil from both sides of each washer. The cylinder head and washer mating surfaces must be free of oil/grease/lubricant. Failure to keep these surfaces dry may result in inconsistent preloads.
6. Place the washers over the studs and on to the dry, clean spot faces of the cylinder head.
7. Lubricate the stud threads and bottom of the nuts with ARP Ultra-Torque Fastener Assembly Lubricant. Then install the nuts onto the studs and tighten hand tight

• Premium Material: The studs are manufactured from premium grade 8740 chromoly alloy steel, which is rated superior to "aircraft quality" material and heat-treated to a formidable 200,000 psi tensile strength.
• Superior Manufacturing Process: Each stud is cold-forged to ensure molecular integrity and then heat-treated vertically in special racks for complete and even heat penetration. This is followed by a centerless grinding process to make the part exceptionally straight and thread rolling after heat-treat, which provides significantly better fatigue strength than less rigorous manufacturing methods.
• Optimized Clamping Force: The design helps prevent head gasket failure by providing a more consistent and even clamping force across the cylinder head, which is crucial for high-performance and high-boost engines.
• Reusable Design: Unlike the factory torque-to-yield (TTY) head bolts, ARP head studs are reusable, simplifying engine assembly and servicing.
• Convenient Assembly: The kit includes compact 12-point nuts for easier installation in tight spaces, along with hardened parallel washers for even load distribution and accurate torque readings.
• Complete Kit: Each kit comes complete with the necessary studs, 12-point nuts, parallel-ground washers, and a packet of ARP Ultra-Torque Fastener Assembly Lubricant.
