I think you would be fine up to a 1.84 w/o valve float from what I've read.
I ordered a set of 1.9 modded stockers for my sons GTP during ZZP's woot sale and got, springs, retainers, rocker install kit for $3.
We have no intention of using any of that stuff except for the rockers.So yep I may sell the additional items to help offset what he had to pay for the rockers. The only thing potentially useful to me may be the springs, but I doubt I'll have to replace them on my car.
