Do ARP head studs need to be torqued?
Do I need to re-torque my head bolts or studs? If you follow the ARP installation instructions, there should be no need to do a re-torque. However, it may be necessary under certain circumstances if the gasket manufacturer’s instructions require it, particularly if a fire ring has been installed.
How are ARP bolts measured?
All ARP connecting rod bolts have a small dimple placed on both ends of the bolt that accurately position the rod bolt gauge pins on the bolt. Next, zero the gauge on the relaxed bolt. Then you carefully tighten the rod bolt until the gauge reads the appropriate stretch amount.
How tight should head bolts be?
In most applications it is necessary to first hand-tighten each bolt snugly until the head of the bolt is flush with the cylinder head surface. The bolts are then partially tightened to approximately half of their recommended torque loading in the order specified by the particular engine’s manufacturer.
How many times can you torque ARP head studs?
Generally bolts/studs that have a specific torque value to tighten to are reuseable, but bolts that you torque then turn an extra 1/4 turn or a number of degrees are torque to yield bolts and shouldn’t be reused more than once.
