The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.
The factory service manual is the only way to go.

I really really really hope you turned the bolts an additional 90 degrees after torquing to 22 Ft-lbs. Otherwise, you may be taking that head off again.
Best of luck,
