Default cyl head torque...

From the chilton's manual.

Step 1 - 44 lbft
Step 2 - tighten additional 90 degrees (1/4 turn)

Manual says to use new head bolts...

and the pattern starts in the middle and works it's way out like most other patterns.

Maybe this sketch makes sense...

14.........8..........6.........1..........3...... .....9..........11

...Cyl#6....Cyl#5....Cyl#4....Cyl#3....Cyl#2....Cy l#1........Front of Motor

12........10.........4..........2..........5...... ....7...........13


Let me know if that helps.
