Specs needed: STOCK Crossflow rocker ratio & valve lift

[SixFoFalcon]

As stated in the title, I need to know the factory specs for the valve lift and the factory specs for the rocker ratio. I'm not sure what kinds of variations there were over the years in these parameters, but I'm particularly concerned with the early ALLOY Crossflows.

We use 351 cleveland rockers as stock replacement and there 1.73:1.
