Correct you are! I meant to say tighter on the 69Z cam, not the LT-1 cam. I still think you won't see any difference due to the rocker ratio. I've tried them on a couple different engines and haven't seen any noticeable difference, although not with this exact cam swap.
Maybe someone has done this exact swap.
