Dropped Valve Seat Rebuilds

I'm rebuilding a SOHC 2.0 SPI and have less than complete faith in the specifications provided by our trusty friends at Fel-Pro. Could I get a few second opinions on the torque specifications and end sequence for the Head Bolts? I currently have them all at 44 ft/lbs and will hold sequence until a consensus of the SPI gods has been made. Thank you.

Here's what my haynes manual says (I would also be interested in what the FSM says too if anyone has it...):

1) Tighten to 37 ft-lbs in special sequence pattern starting from the center going to the outside
2) Loosen half a turn in reverse pattern
3) Tighten to 37 ft-lbs in forward pattern
4) Tighten 1/4 turn in forward pattern
5) Tighten 1/4 turn in forward pattern

Doesn't really give a final torque but 44 seems ball parkish.

[edit - changed word "star", not really a star pattern, but starting from the center and moving out pattern]

Dont do the star pattern, do what the manual says as far as the head bolt numbers go, this is very important!

Yeah, it's not a true star pattern. The haynes manual does have the certain sequence. I was using "star" as a generic term. I edited my reply so as not to confuse anyone else that comes along and reads it.
