You need 50/1000s over the lift of the cam for your spring ... you listed .640 lift on the exhaust lobe...that is why I suggested the .700 lift PRC Extreme springs. What is the application for this big azz cam??...one place you do not want to cut corners is in your vavle train especially with a large cam.
would these work safely? https://www.patriot-performance.com/...0&cat=0&page=1
nothing wrong with a little bit of insurance when running a big cam. peace of mind never hurt. some people even run duals on low 230s cams.
Without a doubt you should consider the new PRC EHT springs. They're a complete redesign from the platinum/gold/xtreme springs old stuff. They are built using much better material & as a result have been tested to have greatly longer life & they won't shrink when installed on increased lift camshafts.
For the money the EHT PRC spring kit is worth it's weight in gold. If your on a budget the new .660" PRC spring is a redesign that's still a good bit better than the old platinum or extreme springs. They were redesigned to not have shrinking issues at .650", but they won't last as long as a EHT spring.

I like those too alot.
But the poster has a BIG cam.
The duals might be better.
I have a good deal on a set of some of the best valve springs made.
