spark plugs

I opted to use a torque wrench to install my plugs. Unfortunately, I interpreted 25 Nm as Lbs. so have over tightened them. Rather than 18-20lbs, I've gone 25 lbs. The engine has not been run, but I have certainly crushed the plug seal rings. Should I loosen them, get new plugs/rings, or leave them as is?
 
Leave them as is. ive never torqued my plugs before just tighten them up and go to pretty snug there is no way to hit the piston if that's what u r worried about unless they r the wrong plugs
 
No worries... I've read Yamaha service manuals that just say to screw in the plugs until they touche and then turn so much more to seat those seal rings. IF you spec was 18-20 lbs and you went 25lbs no big deal. To reach 25 lbs ya only turned it a touch more. Leave them and go have fun as Opti-man said.
