    Head bolts\studs for 470hp

    I have nearly all my bits for my gt30 build.
    For those with big power was wondering what head bolts you have used?

    I have heard the arp ones have known to lift ?

    Cheers !

    ARP's in mine and they haven't lifted and i doubt they will. Never really heard of any lifting and i know a good few people who use them. So long as there put in correctly to the correct torque settings you will be fine IMO. I actually think i used the ones for a C20LET in my Z20 IIRC

    ARP are about as good as your going to get, have them fitted to a 500 + bhp zlet with no problems, thats using a gt35.
