Manufacturer torque spec

• 1. Inspect all hardware prior to installation. Look for obvious defects or shipping damages. Please call 800-826-3045 with any questions or issues.
• 2. To ensure proper thread engagement and accurate torque readings, clean all threads in the block. Chase if necessary with ARP Thread Chaser, part number 912-0011 (M11 X 2.0) and 912-0001 (M8 X 1.25).
• 3. Clean the spot faces on the cylinder head where the washer seats, use of solvent or brake/carb cleaner is recommended.
• 4. Install the head gasket and cylinder head.
• 5. 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. Install the 8mm studs in locations 11-15.
• 6. 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.
• 7. Place the washers over the studs and on to the dry, clean spot faces of the cylinder head
• 8. 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.
• 9. Following the manufacturers recommended torque sequence.
• NOTE: See instructions that come with bolts or in this products description for torque sequence.
