Chrysler 2.4 Valve Springs For Use In 420a?

I'm wondering what the stiffness difference is between the 2.4 valve springs and 420a valve springs, and also if they're similar in diameter & height? I know the best way to figure this out is to remove both and do a comparison, which I'm willing to do. Just thought that possibly someone has already looked into to this and can save me a little time or money. Here's some pictures of a 1996 Stratus 2.4 that I was pulling from at the yard today. To me, the cylinder head looks almost identical to the 420a ("reverse flow" of course). If this is a bust I'll just buy the BC springs I was planning for anyway.

I believe they're the same part for both the 420A DSM and 2.4L PT Cruiser: 04777555AB.
2x on this. But its not a 100% total bust. If you're ever needing to grab a few stock replacements from the junkyard it's way easier to find PT's and the cams are a lower lift so less wear than a 2.0. And they are newer to boot.

But with Crower springs selling for 75 bucks a set I'd probably just go with those. Lol

Those are great points.
