It might require less timing to prevent detonation. Ages ago I had some friends who both had very similar 360s. One was 10.5:1 with KB pistons and quench was paid attention to. The the other was 9:1 no attention paid to quench. The quench engine was almost a full second faster and could run more timing than the lower compression engine.
Good to know.. right now I need to check the exhaust pocket depth to see if I can mill them deeper
and still have enough material in there before I can make any decisions.. might be easier to get
some other pistons if cheap enough.. I will sonic check them in a day or so
