What spark plugs should i use 66 dart 170 base 2.8L engine?

I grab the ring washer with a regular slip-joint pliers, put the spark plug socket/wrench on the plug, and just unscrew the plug from the washer. It's a little stiff at first, but nothing gets damaged.

Thanks that did the trick! Now the 66 dodge_coronet FSM says they should be gapped at .035 , Im guessing thats for any plug you put in. They seem to come out of the box at .035 if I'm reading this correctly. Am I on point here? Also, Should I use dielectric grease on the new plugs I'm putting in as well?
