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.
