Some 5.9 roller cam help from y'all please

I'll spare ya the gory details :D but it's a little late for that if I already have the heads and seeing as they don't go over .470 I'm not capable of spending 1,500 on daily driver heads.
Well, capable but not going to.
I'll run it with the stock cam before I'll do that.
I know there is an acceptable way to use what I have and make it work well for what I use it for, just trying to find it.

We have the spring kit that will bolt right on your heads you have and allow you to run up to .570". Your not limited by your heads, its the 80# springs that will bind at anything over .475", the heads will take a huge cam. Springs, retainers and locks are less than $200.
