Head bolt torque specs

I am just wanting to make sure I am doing this right.

Chilton manual says to torque head bolts to
1. 37
2. 42
3. 50
4. 59
5. then loosen bolts 2 turns and the re-torque
to 59
6. then turn bolts an additional 90-110 degrees

Does this sound right to anyone?

Thank

I don't remember if you loosen them a whole two turns, but I know I went an additional 110 degrees after final torque.
