Help me with some math Please

DO NOT average your chamber cc's, you are calculating for the least cc measured, 'cause that's the cyl.(s) that will detonate first. When power timing your eng., 6 cyls. out-
weigh 2cyls., for instance. In other words, if you have 6 at 86, & 2 at 84, the eng. output will continue to improve as you bump the timing even tho' 2 cyls. have reached or
crossed the detonation threshold. I cc'd a set of 906's for a 6bbl.440 job, the chambers for positions 3&6 on both heads were shallow, enough that I corrected them B4 I
proceeded. Examining the pistons showed Me, #3 definitely showed the telltale pitting of det., #6 not as bad but.......
