Thanks for clearing some of that up. Anything to look for with bases? Materials wise?
And valves, are they worth replacing/ upgrading?
Yea I'd say the standard set of spring rates would suffice. And I'm unsure of the bases material but I'd be more than willing to bet that whatever the standard is, is fine. I'm running the supertech kit and they are still good to go 3 years later.

As for valves that's a topic I know little about.
I've got custom Manley race valves in my new engine per the builders request. +1mm all around I believe. Oem with just spring and retainers are fine also. I have a few friends running the combo making good power and no issues to date.
