head bolt torque

ok...one vote for one round of final torque value, and one for going through the sequence multiple times at final torque value...

i got to thinking....you are supposed to torque in at least 3 stages up to final torque...well, the closer you get to it, the more the steel shim will be compressed, and by the time yo get to final torque, it should be compressed well, so it shouldn't need multiple passes through the sequence....

i'm using 4 rounds to get there....20, 40, 60, 70....don't guess i'll have a problem
