Even with Intel's copy-exact policy you can't copy-exact the people, just the toolsets and the protocols by which the people are supposed to operate.
But even still remember one objective of a fab is to maximize yields for sellable clockspeeds. The Q6600 sells at 2.4GHz, not 3.6GHz.
There is no reward system in place for motivating engineers to figure out how to increase Q6600's overclocking ability...so if a decision gets made internally to change something about the process in order to increase yields on 2.4GHz parts while at the same time that decision results in reducing the maximum clockspeeds of those 2.4GHz parts to a mere 3GHz then no one is going to lose their bonus check over it.
