how to fit arp head studs?/ how do i recognize a -31 actuato
some people no longer recomend the use of the short ARP studs - stick with the standard headbolts, or fit the long studs from Mountune.
"31" are the last 2 digits of the part number of the "-31" actuators
"31" are the last 2 digits of the part number of the "-31" actuators

A -31 actuator will have '-31' etched on it somewhere along with the part number. If your actuator's a little grubby (mine was), a bit of Gunk and a toothbrush will bring out the numbers so you can see them.
