Speaking of Springs for Magnum Heads and Hyd cams.....
That number is based on an installed height of 1.7" and the factory magnum installed height is 1.64" I believe. Looks like the actual coil bind height for that spring is 1.15" based on trick flows chart. I could be wrong but with 0.06 that only gives you 0.43" of lift max.
I've been doing the same research trying to find a better spring but I'm coming up short.
