SKU(s): 800FC0025
INCLUDED PARTS
(1) Custom Age 625 Head Stud
Kit
-(8) 10mm Head Studs
-(8) 10mm Washers
-(8) 10mm Nuts
-Assembly Lube
INSTALLATION STEPS:
Remove (1) factory head bolt and replace with (1) ARP 625 Head Stud 10mm. Apply supplied
assembly lube to the top of the stud threads and both sides of the washer and nut. Install
washer first, then thread nut onto the top of the stud - torque nut to 45 ft lbs. Be very careful not
to drop anything into the engine! NOTE: Do this process one at a time for all remaining head
bolts. Never loosen more than (1) head bolt without replacing and torquing with a stud.
This will ensure the cylinder head gasket does not lose its seal. Once all factory bolts have been
replaced with studs, torque the head according to the “REPLACEMENT” pattern and torque
steps below. When all studs have been torqued to the final value, re-torque to the final value (3)
more times.
NEW GASKET INSTALLATION:
NOTE: If the engine is disassembled and a new head gasket is being installed, see the “NEW
GASKET” torque pattern and torque below.
Please refer to the shop manual for removal and installation and timing the camshafts.
● To ensure proper thread engagement and accurate torque, be sure all components are
clean and free of debris.
● Use the supplied assembly lubricant on the top side of the stud and between the washer
and nut.
● Hand tightens the stud until it lightly seats into the block.
● Install the washer and nut then torque as listed below.
