I torque everything that has a specification. I find that even after decades I tend to over tighten smaller fasteners (< 3/8" or so) and under tighten larger fasteners (> 3/8" or so). I've gone to grade 8 on any 1/4" bolt as I pop the stock fasteners like candy. Intake gasket end rails on a BB as one example. The only notable exception is the oil pan. That I use gasket compression to know when to stop.
What is the torque spec on an air cleaner wing nut, hose clamps, and trim screws? After all, you said you used a torque wrench to tighten them, you must know.
