Hello,
I came across this good article on Valve springs for mopars, I noticed its been taking down now and all the info gone, I have a copy of it here in PDF if anyone is interested. Below is what I found most interesting about the magnum engines
I thought it was rather good how you could get .600" lift with using the right combination of parts, .600" should see most street cars covered with a big cam.
Now it's archived here and can't disappear from the web.
Thanks
Bruce

RECOMMENDATIONS
Keeping all these items in mind, the HP spring for the big block engines (383 & 440) and for the 426 HEMI Gen II engine is P3690933 (used in production on the 426 HEMI engine and 440-6BBL). It is good for cams with up to .500″ valve lift. The HP Magnum and 4.0L Jeep vehicle in-line six-cylinder spring is P5249464, and is good for .525″ – use P4876062 for lifts up to .600″ (both use retainer P4452032).I thought it was rather good how you could get .600" lift with using the right combination of parts, .600" should see most street cars covered with a big cam.
