I may also try a set being I usually start with new set of plugs anyways I have used NGK in the past but never really tried back to back test before with them one question I have is a lot of people are recommending heat ranges based on compresion ratio alone but isnt cam selection a huge factor being cylinder presure is determined largely by cam duration and compresion ratio. just a thought

11:1 which it is based on the area its a good place
to start... thats why I said I'll see how they act
