    yeah, you just fucked up. if anything its not as tight as it was b4. Your going to need to get a new set of head bolts, they are like 20-30 shipped. This is a very easy job since your not removing the head. Dont go cheap around this kind of stuff.

      I just went through this. Replaing the gasket and using new bolts didn't solve it. I think the head's warped.

            new gasket, new bolts and shaved head + proper torque sequence = no leaks.

                  There's no final torque spec. Also, they're stretch bolts so you can't retorque them.

                    +1 for stretch bolts I'm surprised no one said that awhile ago

                      It was said, several times. TTY= stretch.

                        How dose any one know if they were stretched properly to begin with? and What dose he have to loose, checking the 90 lb torque to start? GL
