Dual Valve Springs and Cam Break in Question
I just installed a new comp cam and need to install the .675 lift dual springs. The installation guide says to remove the inner spring from the dual valve spring set up and install. It then says to run the engine 30 minutes and afterwards reinstall the inner spring. Is this required?
If so, can I use the stock yellow 243 springs for break in and the install the duals?

The break in is for the spings not the cam. I don't know about the .675 break in but it sounds odd to have to pull them off again what a pain in the ***. I have the .650 lift spings and it was just a few heat cycles to break in.
