    Theyre torque to yield bolts. Really only supposed to be used once. If your in a strech you probably could get by fine with them, like many others have done. If i were in your shoes, id shell out the 30-40 for the ARP ones. Those will last you just about forever

    I would not do it.
    We had a guy blow two head gaskets on a NA car !!

    He re-used the bolts !! :lol:

    Cheep insurance to get new ones.

    I would not trust my 200K bolts, too much work to pull the heads TWICE. IMOP

    I agree buy news ones, because if you blow another head gasket it will cost more to fix that than it would of to just buy new bolts.

    Get ARP headbolts! I put stock heads on with the same head bolts (one snapped off in the block while torquing them down) and i just put on ported stock heads, i found that a headbolt snapped, and i blew the gasket, good thing i caught it, or i would have ruined my block! i immediately went and bought ARP head bolts, no regrets...i paid $50 atm y local speed shop, i didn't have time to order some

    7/16" is the size that you need. NOT 1/2"

    now if you have already had the heads off and replaced the stock head bolts with arp's, would you replace the head bolts again?

    do not do that. Once they are on there, you have compressed your head gasket, if you remove them one at a time and put new ARP bolts in, they have a different tinsel strength, so you will be torquring them slightly different, and it will cause seals to blow. I know this, my buddy tried it :)

    And plus you could break a stock headbolt in the block, and you will be wishing you put ARPs in!

    Technically you CAN because they are the same size :D but dont, ARP bolts are not expensive and they are a huge investment.
