I Recently removed the head off of my inline 6 flat head (g series) I have looked around and can not seem to find torque specs for this engine. Does anyone know where i can find them?

Stu, I think he is wanting to tighten the head. Are those 1/2 or 7/16 head bolts, or studs?

According to the G Series Engine Repair Manual I have the cylinder head torque is 50-60 lbs. Not sure why the 10 lb range. Instructions include starting at the most centrally located nut and tighten alternately from side to side.
