Reusing ARP Headstuds on boosted Motors
Was wondering what the rule of thumb , or the norm on how many times is safe to reuse ARP Headstuds on a boosted race motor. Does this number include periodically retorking the head? was just curious.........

Re: Reusing ARP Headstuds on boosted Motors (K SERIES)
I have been using ours on the race car for 3 years...prolly had the head on and off 30 times with no issues. They should be good to go for unlimited use...

Re: Reusing ARP Headstuds on boosted Motors (ninesecrx)
not sure if i can give a good answer, but ive reused a set a lot of times.. actually the ones i have in my motor now have seen about 5-6 different set ups this year... only problem i ever had was i over tourqed one at the track cause the head was seaping and it twisted the actual stud

As long as the stud/bolt has not been overstretched and no signs of galling or thread elongation, it is reusable. Of course, if you've gotten a season or two and/or numerous head r&r's and had no problems you've gotten your moneys worth and should replace them for peace of mind.

i even called arp and they said the same thing </TD></TR></TABLE>As long as you don't over torque them past their yield strength, they should be fine. The torque specs you get from ARP are normally about 75% of the fastener yield strength.
