Default Head Torque Question

I went and tightened all the bolts down to 22ft/lbs (in the right order), and am now about to begin my final round of torquing. Can i tighten all bolts to 65ft/lbs? Ive seen some guides say tighten them all to 65ft/lbs, other say turn them another 80 degrees, but i feel like torquing them all to 65ft/lbs would be more accurate, and easier for me to measure. Any suggestions? Thanks guys

Take a look at that. Should clear things up a bit. Actually i just used it to put my heads on yesterday hehe... Its directly off the General Motors service information site that we use at my dealership and in class in my GM ASEP program.

65ft lbs is the norm for most aluminum headed small block Chevys.
