INSTALLATION METHOD FOR PRO SERIES HEAD BOLT KITS
Part Number: 234-3722 Application: SB Chevy with 18° Hi-Port heads
1.
Always verify the part number for your application with the part number on the side of box and the part
number on the instruction sheet. This will help ensure you have the correct installation procedure for
your specific application before installing any components.
2.
Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit,
length and dimension.
3.
To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if
necessary with ARP Thread Chaser, part number 911-0004 (7/16-14).
4.
Position the chamfered side of the washer on the bolt so it faces the bolt head. This is done to clear the radius on
the under head of the bolt. Note: Improper installation of the washer will cause premature bolt failure.
5.
If the cylinder head bolts protrude into a water jacket, lubricate the threads of the bolts with ARP THREAD
SEALER.
6.
If the cylinder head bolts protrude into a blind hole, lubricate the threads of the bolts with ARP ULTRA-TORQUE
FASTENER ASSEMBLY LUBRICANT.
7.
Install the cylinder head(s) and check for binding or misalignment.
8.
Lubricate the under head of the bolt and the washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY
LUBRICANT. Then install the bolts into the cylinder head and tighten them hand tight. ARP recommends using
the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed
to motor oil. This is due to higher friction on the bolts as well as inconsistencies in the clamping force of
the fasteners when motor oil or other low quality lubricants are used.
PRELOAD (TORQUE) RECOMMENDATIONS
9. Following the manufacturers recommended torque sequence tighten the nuts in three equal steps to the following
specifications with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
7/16 bolts 80 ft lbs
7/16 X 3/8 studs 55 ft lbs
Note: ARP Ultra-Torque Fastener Assembly Lubricant has been specifically designed to reduce tension preload scatter and
eliminate the need to cycle high performance engine fasteners before final installation. ARP Ultra-Torque far surpasses all
requirements offered by previous ARP lubricants in terms of fastener preload repeatability and performance lubricating
properties. For more information on ARP Ultra-Torque visit our website at www.arp-bolts.com or call 1 800-826-3045.
