Ok, that makes more sense. Because I thought that my pedestal mount 1.72 rockers I had on my stock motor brought the stock lift of .444 up to something like .477. You're talking about a few thousandths more with 1.72 vs. 1.70s. It's hardly worth figuring it out. I don't know the exact formula but I'd imagine the 1.72s raise the lift something like .32-.34. I'd go for the 1.72s.
