Question about torquing vortec heads.

[Asterios Anagnostou]

Hey all,
I have a question about my 96 sierra 5.7l vortec head job. I bought a brand new quinn torque wrench with a built in angle system to do the job. After you reach the angle you want, it tells you what torque you reached. I cleaned the threads before installation to ensure smooth insertion.

I torqued both heads (22lb/ft first pass, long 75d, med 65d, short 55d second pass), but what's been bothering me is the variation in all the torque values I got after completing the angle adjustment. I know the ultimate goal is to reach a certain stretch right? Also there's the fact that it's impossible for me to be absolutely consistent with a wrench that beeps at me versus one that clicks haha. That introduces slightly more variation.

I've read in other places to verify torque after finishing up, but how the hell do you even do that? Any help would be appreciated.

did you put oil on bolt threads , and under head washer , that helps even out the torque
