67 twin turbo dart

Well measured the oil 10.5qts not sure why they put that many, cam plug looks dry aside from flinging, looks like the oil pan is the leaker between I forgot silicone on the front and rear half moon shape seals and the over full oil. What are you all gapping your plugs too, I checked what they put in and its .025 is this good to stick with? Thoughts?? Suggestions?
