No way in hell are the misfires related to torque values. Look at what changed when the plugs were
swappped out. Connections were broken and restored, etc. I've had overtightened and undertightened plugs fire just fine; now the thread damage in the heads or low compression were another matter entirely...

Last set I bought were not pre-gapped. They were anywhere from .024-.032. Not one was
correct. So if they are pre-gapped why were they all different then?
Could it be due to them not having the plastic protector on them?

They are side fire plugs, and the arm is solid, very non bendable.
Maybe the plugs you speak of were not the famous F5DP0R's, because they simply can't be gapped without MAJOR force.
