I've heard its not good to reuse them because they stretch when you torque them, i will be selling the car so wud it be really important to get new ones????

 

Hyundai says Beta head bolts may be re-used without limitation. If I recall correctly, they also say to torque them, then rotate them a specified number of degrees, then rotate again. There is a special tool to monitor the angle.

 

Never reused head bolts in my life.



I don't care what Hyundai says, not worth it to save less than $10



And the "specific number of degrees" is called a yield, just so you know

 

+1000

 

Do you change your shoelaces when you put your shoes on every time also? Unless you are running big boost, re-using stock head bolts is a perfectly sensible way to save a few dollars.



edit: maybe once or twice. It would give even me the heebie-jeebies to re-use stock head bolts like 5-10x but then I also can't think why I would have the head off that much.

 

stocker do you knw where i can find that info at???

 

I dug it out of Webtech back when I started the head work on my spare cylinder head many, many moons ago.

Google did find MadJohn saying they use stock head bolts on high power builds in Korea

head bolts are actually a lot more than 10 bux, when i bought mine they were like 4 bux EACH iirc



i personally, wouldnt reuse em unless i absolutely had to

 

very helpful info stocker,



headbolts were 58 bucks but it was a special order so i said f*ck it.lol

 

Personally I would NEVER reuse stretch-bolts. Never ever ever no matter who tells me otherwise. That's me though, do what you want.
