When tightening NEW head bolts, the service manual shows a three step process.

I tightened them in order to 31 ft lbs. Step two and three indicate retightening to an additional 85-90 degrees each step. Is this an additional 170 t0 180 degrees TOTAL, or is it an additional 10 degrees meaning I tighten it FROM 85 degrees past 31 ft lbs TO 90 and then again for the third step?

I know I'm probably over complicating this, but there is a HUGE difference in the amount I tighten depending on how you interperet it.....

 

After you torque the bolts in the first step to 31 ft-lbs., you then torque turn all of the bolts in order 90 degrees. Then another 90 degrees in order. It ends up being a total of 180 degrees, but you MUST NOT turn all of the bolts one by one 180 degrees after you torque them to 31 ft-lbs. Step 1. Torque to 31 ft. lbs, Step 2. Torque turn 90 degrees, Step 3. Torque turn another 90 degrees. Hope this helps.

 

Definitely adds clarity. On the crank pulley, there is detailed info on the 4 step tightening order. On the heads, there is too much room for interpreting what the f they want you to do.

Thanks.....
