I've tried to do a search on these and didn't really see what I want to know.

I have a set of the old,non bushed, Comp steel rockerarms. I used them on my old solid roller cam at .648 lift with no problems at all. I don't remember what the spring pressure was though.

I'm wondering if I can still use these on my new solid roller at .680 lift and 715 lbs over the nose. I don't really want to buy new rockerarms.
