5.2 Magnum valve springs ? Stock type replacement ?

[rustytoolss]

Just wondering if there are any factory stock valve springs that can handle some added lift and RPM ( nothing for big cam needs/ just some added beef and psi ) over the factory 5.2 magnum VS . Ford, chevy, mopars....boneyard stuff ( without needing machine work to fit.)

I have no parts books of the appropriate vintage, but I *believe* the only Magnums that may have come with different valve springs MAY be the '98-'03 Dakota R/T.
But if you manage to find one of those in the boneyard, I'd be grabbing the entire engine and not just the valve springs.
Otherwise, to my knowledge, all 5.2 and 5.9 Magnums used the same springs.

This is about as cheap as you’re going to get…

Just be careful as the guy just joined on Dec 19th 2025!!!
