I am looking for advice on a set of valve springs for ZZP's ER rockers.
GM's 90lb yellow springs seem common but I am looking for something that wont screw my timing chain and dampener. Any recommendations?
My push rods may also get replaced. Stock length and 5/16". Are Intense lightweights okay? Comp Cams? Any other options?
Are zzp's modified retainers or intense, Manley LS type retainers a good idea? Are new valve locks necessary?
I will also be using Viton valve seals and ZZP's rocker install kit.
Thanks for the help.
