i would have to say no do not try it set up that way,, those springs are rated for .650 but others say when measured .620" is the max lift they should be used for,,, since you have them installed .054" less than the factory 1.800".
so if you take your cam .584" + the .054" = .638" actuall lift applied to the spring
if you set them up at 1.800" you would be fine

You can get retainers or locks that can give you .050 or more installed height. I'd call Patriot and ask what they recommend. I'd had machinest' sink the valves to get correct installed height >>>>>> BAD move....
