Hi i have just had a disaster with a head job, dont know why but on test run it went bang and 7 of the 14 head bolts broke free from the block.

Can anyone give me their version of the torque settings as i am wondering if i could have overtightened them. I got my info from the autodata book so i cant imagine it being athe problem. The bolts were reused could this have been a factor. (they hadnt bottomed out)

Toque setting would be great and i can compare them to check if they are the same.
Regards Brad
