Vortec heads torque specs

I am looking for the torque specs for a '96 5.7 vortec cylinder head. Also the sequence would help too. I know starting from the center and working your way out. I would just like to see if anyone know where I might find a printable version.

When did Chevy start using torque-to-yield head bolts? Are you using standard bolts or TTY? The chart given is good for standard bolts.

I am going with the factory bolts. I was told that you can reuse them without any problem.

I wouldn't reuse head bolts because they fatigue over time from heat cycling. The expansion and contraction causes them to yield. Once they start to stretch the clamping force is diminished at the same torque value.

I'm guilty of re-using mine several times--even re-use head gaskets sometimes!!
