I have never seen the need to do this, I take reasonable care of my engines. I usually average between 10 an 12 gallons between rebuilds running 30% nitro. I just do a standard heat cycle breakin that was taught to me by Ron Paris (a long time ago). I also run .021” of deck clearance to prevent detonation, the old rule was .006” for every 10% nitro you are running. I run .003 extra just to make it a little easier to tune.
