According to this you have to run 1.1:1 rockers only with the 407s . My question is what would be the advantage or disadvantage with running Ratio rockers ?

My friend ran a 407x1.1 on his 69x88 with F/F heads and 48s and gearing with good results [12.90+13.00] in his street 56 bug back in the early 70s and den I ran that cam for a few years with 1.25s with no problems so I can say that with 1.25s is no problem if the heads can handle the extra flow or else it"s a waist.
