hey wats good ive been getting mixed answers about this. can arp head bolts be reused ? some people told me yes and others told me know so wats everybodys opinion thanks

 

Everything ARP can be reused but if you pully a head off 5 times within a year after the 5th time i would get the bolts measured just for insurance.

 

Sure. I reused a set on a 400whp turbo car 6 times total over 10k miles before replacing them just to be safe.

Some people have stated that they need to be replaced every time they are broken but I went inside my motor so much I figured I would see how they held up. Car car 18-20 lbs of boost daily for almost a year and the head was off 6 times in that time period. Never had an issue with the headgasket sealing so I would have to say they are fine.

 

Studs can be reused. OEM stretch to yeild bolts should not.

 

ok another 2 questions are all arp head studs the same length cuz the ones i have are a 14 inch longer than the oem ones? and when you put them in the arp faces upwards rite ? ok thanks everyone

 

They are not all the same, GSR/LS will be longer than B16 and so on.

What do you mean 14 inches longer?

And short threads go up, long threads go into the block. Or rounded end down, allen head up, depending on what you have.

 

lol my bad i ment a quarter inch longer then the stock oem studs
