Re: Once again... Valvesprings & retainers
Those are for a 5.2/5.9L Dodge IIRC.
They have a larger Outside Diameter and Wire Diameter. I believe the chart shows this also. I am not sure if that will require machining to the head or not. Im sure others will chime in.

If it feels right, then STROKE it!

Re: Once again... Valvesprings & retainers
Probabaly more people hopping up a 5.2/5.9 to the max that would need a higher lift spring. Just a guess. What are the spring rates and seat loads on those compared to the 464's? Are they stiffer?
