fair enough.
i have always used 165 as the standard as thats what a new 308 "crate" motor would get, and anything less than 120 means there is a problem - usually just needs valve relap.
totally agree on the cams, they are only good for 150000 km in my opinion - this goes for the v8 chev stuff too..
