Not sure, but I dont think they are supposed to snap.
Did you use new head bolts? Did you get NM and ft-lb mixed up?

why are there different numbers for different bolts?
 i thought the head would have wanted to be torqued down evenally.
and no their not meant to snap 
as above, did you use new bolts?

i thought the head would have wanted to be torqued down evenally.Because you don't torque them all the way to start with, your torque in stages, so the first number is the first stage (torque all bolts to this in sequence), second number torque them all further to this and third torque them all to that to finish it off. I'd say if you used second hand headbolts there's your problem, or if you used new ones the quality was crud! |
