Can I get away with using stock valve springs with a 472 lift cam? I'm temporarily going to run a set of 906 heads with this cam. I don't really want to change valve springs, retainers ,seals ect if I don't have to.
I'm not sure, that cam is 20+ years old 516 heads have bad seats, seals and I have a set of decent 906sWhat does Erson recommend?
