Just thought I'd let everyone know.... I re-used the stock head bolts on my head swap to see if they really can be re-used since no one has the balls to do it and torqued them to 70' lbs. So far I have well over 500 miles on the head swap and have had 0 problems with anything! So for those of you who say not to re-use the old head bolts listen and learn!!! However.... I would never re-torque with the old bolts using torque to yeild or they WILL break! If 70' lbs is good enough for an ARP head bolt than it's good enough for a stocker! I'm also putting over 400 to the wheels an running 10.9 CR. |
Lots of people have done it with no problems. There is always that 1 chance though. |
Good luck in the future.... |
A whole 500 miles, congradulations. |
Why? What was your motivation, the $35.00 that new head bolts cost? |

lol let us no in 5k if they lasted |
It's only been 500 miles. I don't see why you wouldn't spend $30 to buy new bolts and be certain everything will be ok 20k miles from now. |
i bought arp and will never have to buy another set |

ARP fasteners vs. stock fasteners are like comparing a Ford mod motor to an LS1. Different grade bolts = different tensile strengths. Different tensile strengths will also effect lateral loads(twist factor). The 70 lbs.ft you refer to for the ARP is NOT "good enough" for the "stocker". Two different animals. The stock bolt is designed to elongate or stretch at a much greater value than the ARP. Once that elongation has occured, even torqueing it to 70#'s doesn't necessarily mean that the torque vs. elongation factor gave you that 70#'s. If you want to re-use a fastener as important as a head bolt, buy ARP's and be done w/it. There is a reason GM and all reputable engine builders will tell you NOT to re-use a TTY fastener. Just b/c you pulled a boner :twak: and your junk is still together is not justification to give bad advice. Lot's of newbies here who might actually think you know what you're talking about. I guess "those of us" that do things right, are just stuuuupid. Congrats on saving $35.00. Now..... go back to www.ls1.com :wavey: RANT OFF |

I usually don't do this but I will for this one. How fucking stupid! Do you reuse your oil filters too? :nono: |

While you all are at it, reuse your condoms too- just wring em out and hang em to dry :) |
