From my understanding this modification was used on later 935 heads, just before they started pumping water. I'm running them on my next build, until then I won't know how effective this mod is. I've been playing with higher boost levels on my current build and monitoring temps, you can't keep the heads cool enough thus my decision to use the 350RR heads, valve guide oiling mod. and 930 sodium filled valves.
