did you grease the head bolts?

 

[dantheman]

run a tap down all the head bolt holes in the block, and put a little engine oil on the new head stud threads if they havent come soaked in oil already.

 

[350ep70gr]

You need to divide the nm to 1.356 and the result will be your settings to ft/lbs
Means 22nm /1.356 = ft lbs
44 nm / 1.356 = ft lbs
Then 90 degrees. Use engine oil on the bolts.

firstly 16ft/lb

secondly is 32 fb/lb

then 90 degree turn. will this suffice?

How did you manage to snap a bolt, by putting obviously more than 36 ft/lbs of pressure on it, then loosen it by hand?

Once it snaps there will be no load on the threads so they can come straight out. I've been lucky enough for that to happen, not on head bolts though.
