    OK so the new head has been on for almost 1,000 miles and let me tell ya it runs like a new truck. I'll be taking the camshafts off today to change some of the shims to get all the clearances in spec. I'm wondering, while the camshafts are off, should I bother with re-torquing the head bolts? If so, how much? I have a torque angle meter.

    Thanks for your input.

    Not sure it would be needed but using a torque wrench and doing one click at the correct torque probly wouldn’t hurt.

    On my 86' 22re a guy at the shop told me to retorque the head bolts by loosening one at a time, in proper order, and then torquing them again.

    I neglected to do it, and had the truck for another year and a few more thousand miles with no issues.

    If you used new head bolts I wouldn't worry about it.

    I did the head on my 2rz and havent retorqued the head bolts I just dont want to pull the cams back out. I have 4-5000 miles on it with absolutely no issues, but if you have the cams out like DW85 said not a bad idea, definitely wont hurt.

    That shop guy is a doofuss why would ya loosen and retorque it, sounds bass ackwards I’ve done plenty of head gaskets and I would suggest just to check torque with a good torque wrench. The headbolts should usually be replaced if loosened as they are tty (torque to yeild) means they stretch after tightening. Thats why I wouldn’t loosen. Head bolts should always be replaced, when loosened, unless running ARP studs.

    how do you keep your timing chain from slacking on the crank shaft gear when you have you cams out?

    Hey,

    I just zip-tied the timing chain to the crank shaft gear and it worked fine. As long as the crank doesn't move while you have the cams out it will all go back together perfectly... The intake cam has a notch on it that lines up with the notch on the gear when you put it back on.
