you don't need to torque spark plugs...just use a 3/8" ratchet and bottom out the plug in the bore, then a little snugness. Feel how much force required to loosen and replicate when tightening. No GD anti-seize on the threads either. GM doesn't use it on any factory plug I've personally removed from an LSA, LS7, LT4, LS6, etc.

You are describing the exact equivalent to a torque spec, except you're doing it by feel.

I've never seen anyone in my entire life use a TQ wrench on a spark plug. Snug them up and call it good.

Yea im sure it's probably weird but if your OCD is telling you to at least try and use a torque wrench why not just use it and do it correctly doesn't cost yiu anything or more time.

I believe this is obvious...you don't need to torque plugs to an exact value as I am concerned someone will over torque trying to be "perfect". By feel is the best way for this situation IMHO.
