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
Plug heat range for a particular engine is just a guess on the tuners part , & you're correct regards cylinder pressure , what plug works in one motor running 11:1 won't necesarily be correct for another motor running similar CR , this is why reading plugs will be the deciding factor.
