That must be an old RM article, only .900 lift cam? David, Bruce, and Darrin have tested almost every combination and usually share most of their findings publicly. I would be interested to get his feedback on putting an extra .100 lift over max flow on one of their pro stock motors because you know they've tried every conceivable option. I could be wrong but I think theres more efficient ways to gain area on a head thats basically done at .700 than opening the valve .800+
