head stud question

[aznaccord]

i know this might be a dumb question, but i bought a h23 head and the guy gave me free head stud, since i'mma need it....can i still reused the head stud or it'll be better to buy a new set of head stud?..why do some people says that it'll be better to get new ones to prevent any leak, but its just a bolt tho.lmk thanks

your supposed to use new ones. some people reuse them on occasion, but i would not. better safe than sorry. later.

You can re-use them once after they are torqed down from the factory... but if you don't know the condition I'd just get new ones...

but one re-use is perfectly fine...

Its better to get a new set since over time they stretch. Id just get a new set just in case. You can reuse them but its best to replace them.

Head studs as in ARP head studs or Head bolts as in long ass bolts?

Stock parts are bolts. Studs are upgrades.

Still, I'd just spend the money for new studs. You don't want to risk that.

I know that you can only reuse the stock head Bolts once but what about the STUDS. Like the ARP studs are they stronger and can be reused more than once?

Honestly, I don't know for sure.

However, anything that has prolonged tension has got to warp a bit once the tension is released and reapplied. The stock bolts are MADE to stretch, so they're shot after the second use max... using them more than once isn't the best idea, but it can be done. Studs are probably sturdier, but I wouldn't risk it. A set of studs costs what, just over $100? In the case of stud failure, the LEAST amount of damage you're going to do is blow the head gasket... that alone makes the cost of new studs justifiable!

[ZigenBallZ]

studs... specifically ARP head studs can be reused... how many times? You'd have to contact them and ask...

but that's one of the selling points for getting them...

I would definately recommend upgrading from the factory bolts because as it was stated above, they do stretch, not only over time, but each time they are torqued. They are designed to. It'll be easier, and probably cheaper, in the long run just to purchase ARP or something similar to elimate headaches down the road.

I hear this all the time about using new studs and bolts. We have NEVER used new stuff unless we had to (ie: striped, broken ect.) and we have done many head jobs.

If your worried about them stretching. just torque it down to specks, then put a breaker bar and socket on them and turn it 90 deg. In fact Toyota list doing this in the manual.

Another option is to bump your torque up just a hair. (ie: if specs call for 95lbs use 95.5lbs)
