my bud has a question regarding valve springs.. the heads he has now have some comp cam spring good for a .600 lift cam , he used to have the CC306 cam witch has .540intake and .550ex. with a 1.6rr ,so the valve spring pressure has been set for that cam. but he has changed his cam to a bigger cam with .575intake and .585ex. and dirent change his spring pressure to match the new cam. How can this hurt him in power and will this lead to big problems later on?

Valve flot, maybe break the springs, bend a valve. Buy the springs, no shortcut here.
