INSTALLATION METHOD FOR HEAD BOLT KITS
Part Number: 230‐3601 & 230‐3701 Application: Chevy LS9 ARP2000
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 912-0008 (M12x1.75) and 912-0001
(M8x1.25)
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.
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 on to the dry, clean spot faces of the cylinder head. Place the
stamped side of the washer, see figure to the right, down against the cylinder head.
This stamped surface grips the cylinder head preventing the washer from spinning
while the bolt is being torqued. The result is accurate and consistent preload. The
ID chamfer side of the washer must face the bolt head.
7.
Lubricate the bolt threads and bottom of the heads of each bolt with ARP Ultra-Torque Fastener Assembly
Lubricant. Then install the bolts and tighten hand tight.
