the quench will help keep it from pinging or detonating. not doing it for compression. I`ve got .039 on my 505. we used to run the hemi w/ them slightly kissing just enough to keep the carbon off at 6500- 7000. ran 14 yrs like that.
Ever actually test it on a dyno? I can never tell if it's from compression or quench. Never had anyone close up quench and keep th compression the same.
So, AFAIC if your under .060 and your compression is correct you are wasting time.
