Do a search lots of opinions on that topic, I always do , but I never use a torque wrench when installing the new plugs ,tight and then add 1/4 to 1/3rd turn.

Yes.

Also, when I put that on my spring commissioning list, I added in big bold letters "Don't over tighten! Remember - Aluminum Heads!"

I need constant supervision - even if it's by "younger me."

Can't hurt but can help. Just use common sense about torquing.

Yes, small amount, hand tight, then 1/4 turn to snug. Been doing this for years.
