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.........

 

good question like to know as well.

 

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...

 

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

 

thats the whole point of buying them.. so you can re use them.. reason it uses the stud design.. so you dont strech them..

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.

 

you can reuse them unlimited amounts of time
i even called arp and they said the same thing
