2500 350 ENGINE TORQUE SPECS?

1996 GMC C2500

I am looking for the Torque Spec for a GMC 2500 with a 350 engine. I am replacing a head gassett and am in need of the torque on the head bolts.

You have to do these in sequence, start at 22 ft. Lbs. Then go back, short bolts 3, 4, 7, 8, 11, 12, 15, 16 55 degrees, medium length 14, 17 65 degrees, long bolts 1, 2, 5, 6, 9, 10, 13 75 degrees, not sure how to get a diagram to you on what bolts are where, I have one in my book, there are 9 bolts where the rockers are at, from front of engine they are numbered, 17, 13, 9, 5, 1, 2, 6, 10, 14, on bottom of head by the exhaust manifold is 16,128, 4, 3, 7, 11, 15, this is from my chiltons book on the same model for a5.0 and 5.7 Liter, hopes this helps
