yah i just found it above your post

[jerdalia]

I was reading the Ellerys manual and found the following information for torquing the head bolts:

Coat threads of cylinder head bolts with LOCTITE 243
Cylinder head torque: 58 ft-lb
Tighten a further 90 degree turn of each bolt in sequence
Tighten a further 90 degree turn of each bolt in sequence for the second time

Would it be better to simply specify a final torque instead?. Any comments?
