    I use this rule when installing headers/manifolds... tighten them all down equal and then go back and tighten them all about as tight as you can get w/o feeling the "oh crap im about to break these things" lol
    Works every time. haha

    And if there is a gasket, heat cycle it and tighten em again.

    I just looked at the torque specs and the specs are 20 ft lbs of torque on the exhaust manifold bolts. Start at 5, then 10, then 15 then 20 and go back to tighten them all to 20 again just to make sure they are all at the same torque.

    Well I tightened them at 30 ft./lbs. I hope that's not too tight. I will re-torque them after the first heat cycle...

    No, I believe you. I wasn't trying to call you out on something. Just wondering why it is different. Guess I learned they are different, but wanted to know why. lol
