I am in the process of setting up a 360 LA with Magnum heads.
I have researched the stock Magnum valve springs are there are lots of opinions about using them or not using them....I will be running a .470 lift cam as it stands right now.
Can I use the stock springs?
Engine will rarely see 4000+ rpm.
Thanks!
