My torque wrench doesn't go that low so i just gave mine a "strong nip".
Same here. By "strong nip" do you mean "tight but not as tight as you can"?
I tend to tighten them all so there just starting to nip the gasket then give them all another 1-2 turns starting from the middle outwards. You don't want them to tight. run it up until warm and see if its leaking, tighten if needed.
