What's the best way to do this? Spring pressures, installed heights, spring diameter, how do you pick the right ones? Thanks for the help!

I like to use the super seven or ten degree keepers and retainers on all of my race motors and my street and strip motors Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Although the spring pressures are suitable, a 1.550" diameter spring won't clear the rocker shaft WITHOUT A ROCKER ARM ON IT! Somebody really needs to address the roller sping selection for OEM/Edelbrock heads. (1.46"-1.48")

(1.46"-1.48") I thought that's what drum grinders were for, Its always nice to tear up a new set of roller rockers
